A Study on Comparison and Contrast between IPv6
and IPv4 Feature Sets
J. Hanumanthappa1 and Manjaiah D.H2
Abstract--- This document provides an analysis and comparison
of IPv4 and IPv6 under various circumstances. It is well
understood that IPv6 has been designed to replace IPv4. We have
done a feature-by-feature comparison and contrast of IPv6 versus
IPv4 and found that IPv6 offers many unique opportunities for
increasing a network architectures efficiency and agility. In some
sense, there is a competition going on between these protocols, as
they are not directly compatible, and network providers and users
are being forced to determine whether to support one or both
protocols for various network services. The new version of IP,(i.e.
IPv6), constitutes an effort to overcome the inborn limitations of
IPv4, in order for the new protocol be able to respond to the new
needs as they shape today in the Internet. This paper is aimed to
discuss about various comparison issues when porting an IPv4
application to IPv6 with focus on issues that an application
developer would face rather than a complete API reference.IPv4 is
the incumbent and currently has the most widespread usage for
conventional Internet applications.IPv6 is a large-scale re-design
and re-engineering of IPv4, based on many lessons learned as the
IPv4-based Internet grew and was used in unforeseen ways.
Keywords-- IPv4, IPv6, Multicast, Quality of service (QOS),
HE primary motivation for change arises from the
limited address space. When IPV6 deployed on a large
scale it has solved many current networking problems.
When IP was defined , only a few computer networks has
existed Then the designers decided to use 32 bits for an IP
address because doing so allowed the Internet to include
over a million networks. However, the global Internet is
growing exponentially, with the size doubling in less than a
year. Currently, two versions of the Internet Protocol (IP)
are in use on the Internet. In some sense, there is a
competition going on between these protocols, as they are
not directly compatible, and network providers and users
are being forced to determine whether to support one or
both protocols for various network services. IP version 4
(IPv4) is the incumbent and currently has the most
widespread usage for conventional Internet applications. IP
version 6 (IPv6) is a large-scale re-design and re-
engineering of IPv4, based on many lessons learned as the
IPv4-based Internet grew and was used in unforeseen ways.

Although it would seem obvious that IPv6 is a superior and
valuable protocol to deploy, there is often considerable
resistance to enabling IPv6 because Decision-makers have
difficulty in seeing a business case for IPv6, unsure of how
it can be less costly, more efficient, more productive, etc
than the IPv4 status quo. Also, some analysts have
propagated significant amounts of misinformation about
IPv6 over the last several years. The primary motivation for
the defining a new version of IP arises from the address
space limitation- larger addresses are necessary to
accommodate continued growth of Internet. The secondary
motivation for the changes in IP has arisen from the new
Internet applications. For example, an applications that
deliver audio and video need to deliver data at regular
intervals. In this paper we have also contrasted the various
features of IPv4 and IPv6.
A. The serious problems of IPv4 are as follows
Insufficient number of unique “valid” addresses.
Routing tables at core are becoming unmanageably
Fixed length headers are not flexible enough for new
Packet size (and Practice of fragmentation) is
B. The next–generation IPv6 has some advantages over
IPv4 that can be summarized as follows
(i). Larger address space: An IPv6 address is 128 bits long.
Compared with the 32-bit address of IPv4, this is a huge
(296) increase in the address space.
(ii). IPv6 addressing: An IPv6 address consists of 16 bytes
(octets).It is 128 bits long.
To make address more readable, IPv6 specifies
hexadecimal colon notation. In notation 128 bits are divided
into eight sections, each 2 bytes in length. Two bytes in
hexadecimal notation require four hexadecimal digits.
Therefore address consists of 32 hexadecimal digits with
every four digits separated by a colon. Although the IP
address, even in hexadecimal format, is very long, many of
the digits are zeros. In this we can abbreviate the address.
The leading zeros of a section can be omitted .Only the
leading zeros can be dropped, not the trailing zeros. The
below figure shows abbreviated IPv6 address.
C.Better header format: IPv6 uses a new header format in
which options are separated from the base header and
inserted, when needed, between the base header and the
upper –layer data. This simplifies and speeds up the routing
process because most of the options do not need to be
checked by routers.
D. New options: Changes in the way IP header options are
encoded allows for more efficient forwarding, less stringent
limits on the length of options, and greater flexibility for
introducing new options in the future.
E. Allowance for resource allocation: IPv6 is designed to
allow the extension of the protocol if required by new
technologies or applications.
F. Support for resource allocation: In IPv6, the type –of
service field has been removed, but a mechanism called
flow label has been added to enable the source to request
special handling of the packet. This mechanism can be used
to support traffic such as real-time audio and video.6.IPv6
enables addressing architectures that scale well in terms of
the number of nodes and sub networks, the size of subnet
works, and the degree of change within subnet works this
includes typically-encountered cases where IPv4 becomes
difficult to use robustly. Global routing tables in IPv6 are
potentially much simpler than their IPv4 counterparts, and
thus require lower memory and computational resources. In
resource-constrained environments, IPv6 requires less
processing than IPv4, which can result in reduced power
demands and latencies, especially for routers. 8. The flow-
label in IPv6 is an enabler for per-flow Quality of Service
with simpler algorithms and more efficient implementations
that also permit the remainder of a packet to be encrypted,
all of which are precluded in IPv4. Network and device
security is boosted in IPv6 based on address manipulation
techniques and secure neighbor discovery features that have
no IPv4 counterparts. Routing for mobile nodes is more
efficient in IPv6 than in IPv4. Smooth handover techniques
for IPv6 also exist with no IPv4 equivalents. Current
standards activities indicate that many future features may
be developed for IPv6, but not necessarily for IPv4
G. Support for more security: The encryption and
authentication options in IPv6 provide confidentiality and
Integrity of the packet.
H. Flow Labeling Capability: A new capability is added to
enable the labeling of packets belonging to particular traffic
“flows” for which the sender requests special handling,
such as non-default quality of service or “real-time”
II. COMPARISON AND CONTRAST BETWEEN IPV6
AND IPV4 FEATURE ISSUES
While IPv4 and IPv6 are similar in much of their basic
framework, there are also many differences.
From first glance, there are obviously differences in the
addresses between IPv4 and IPv6. The graphic below
shows an IP address for both versions of IP.
IPv4 Address Example: 18.104.22.168, IPv6 Address
Removing zeros can also reduce the IPv6 address. Zeros
can be removed when they are leading in and within any 16
bit block. The address from the previous example could be
reduced using this to the following representation. Note that
in the example the block of EF00 does not lose its zeros
because they are at the end of the block.
IPv6 Address with Leading Zeros Removed:
2145:D5:2F3B:0:0: FF: EF00: 98F3
Compressing zeros can further reduce IPv6 addresses. A
contiguous block of zeros within a 16 bit block can be
removed. The blocks of zeros are then represented by
double colons:: For example, the IPv6 Multicast address of
reduced to FF02::2 using compression.IPv6 Address with
Compressed and Removed Zeros:
2145:D5:2F3B:: FF: EF00: 98F3 IPv6 performs pretty
much the same functions as IPv4, but in a more reliable
manner, with larger addresses and more flexible and
efficient packet headers. Today the internet has grown to be
a million-network, which is something with startling
consequences. For instance, one of the most publicized
consequences of this growth has been the depletion of the
internet address space. Initially, the Internet’s address space
consisted of 232 addresses about 4 billion addresses. Today,
however, that amount is insufficient, even more if we
consider emerging new technologies such as 3G/4G
wireless devices and other wireless appliances .However
many issues to be considering while comparing the IPv4
The most obvious difference between IPv6 and IPv4 is that
IPv6 addresses are128 bits , whereas IPv4 addresses are
only 32 bits . This increase in the raw number of bits
means that there is a factor of 296 more addresses available
in IPv6 than in IPv4. Due to the way that the address spaces
are sub netted, scoped, and defined for multicast,
private/experimental use, and other factors, the actual
contrast is less direct than this simple factor. In IPv4 the
addresses are 32 bit addresses represented by using three
notation, 3.Binary notation. In Dotted-decimal-notation the
IP address is represented as 10.1.3.7., whereas in
Hexadecimal notation the one IP address is represented as
OX810BOBEF or 810BOBEF16 , whereas in Binary
notation the one IP address is represented as 10000001
0000 1011 0000 1011 1110 11111.
B. IPv6 addressing: An IPv6 address consists of 16 bytes
(octets).It is 128 bits long.
An IPv4 address has 32 bits, whereas an IPv6 address
contains 128 bits. The 128 bits in an IPv6 address are split
between the network and host addresses. There are 64 bits
for the network address and 64 bits for the host address.
Due to the larger address space, the number of available
addresses jumps from 4,294,967,296 in IPv4 to
3.4X10^38) in IPv6. IPv6’s address is also separated using
a different format. IPv4 uses a dotted decimal and IPv6 uses
a colon-hex format. The larger address space allows for
clearer addressing and routing. It also allows for multiple
interfaces per host and multiple addresses per interface.
C. Hierarchical addressing: We will use Unicast, broad
cast, and multi cast addresses in IPv4 .In IPv6 there are
three major types of addresses: unicast, multicast, and any
cast addresses. Unicast addresses are assigned to a single
IPv6 node. Multicast addresses are assigned to multiples
nodes within a single multicast group. Packets sent to a
multicast address must be delivered to all members of the
same multicast group. On the other hand, although any cast
addresses are also assigned to groups of nodes, they do not
need to be delivered to all members of the group—it is
sufficient that one node receives the packets. Additionally,
IPv6 defines a new routing infrastructure that provides for
more efficient and smaller routing tables The IPv6 address
space supports three types of address; Unicast, Multicast
and Any cast. IPv6 Multicast addressing absorbs the role of
IPv4’s broadcast addresses, which is no longer present. The
biggest change is the introduction of the any cast address.
Any cast addressing allows multiple nodes to be assigned
the same any cast Address. When packets are sent to this
address routing decides which node is closest to the source
and routes the traffic to it. Anycast addresses could be
useful in setting up mirror websites, with different physical
locations being accessible through the same Anycast
address. A user trying to access this site would then be
routed to the closest site, resulting in a better experience.
Addressing enhancements result in reduced administrative
overhead. The teaming of IPv6 Neighbor Discovery and
address auto configuration allows hosts to operate in any
location without any special support. Renumbering is made
easier, resulting in less manual attention by support and
network administrators. Renumbering also makes transition
from ISP to ISP or network segment to segment much
easier and potentially seamless. Stateless and Stateful
address configuration assist in making IP configuration and
planning easier. Stateless configuration works without a
DHCP server, while Stateful is a configuration that has a
DHCP server present.
Address Auto configuration allows for a node to make use
of router discovery to determine router addresses, network
configuration parameters, on-link prefixes and additional
addresses. What makes Address Auto configuration so
impressive is that while it requires a multicast capable
interface, it is possible without the use of DHCP. Through
proper configuration and planning, this can reduce the
overhead caused by DHCP management
organizations and ISP’s.
With a new addressing scheme comes a new way of
handling name resolution through DNS. The DNS changes
required to support IPv6 are specified in RFC 1886. As part
of the interim transition from IPv4 to IPv6, it is possible to
register an IPv6 address on a DNS server as an IPv4
address. This is important if a consumer’s ISP has not
moved to IPv6 for DNS and the consumer would prefer to
use IPv6 DNS. The figure below shows a WHOIS lookup
in which the domain has an IPv6 address and is found
through IPv4 DNS.
This example shows a WHOIS registration record from the
registrar Network Solutions. The initial resolution with
Network Solutions is an IPv4 address, the DNS server from
which the record was retrieved.
(i).Unicast addresses: Aside from a few blocks set aside for
local-use, multicast, or other specific functions, the majority
of the IPv4’s 32-bit address space is designated for global
unicast addresses .Unicast addresses identify a single
interface within the scope of a particular type of unicast
address .The scope of an address is the region of the IPv6
network over which the address is unique. With the
appropriate unicast routing topology, packets addressed to a
unicast address are delivered only to a single interface. In
the IPv4 addressing architecture2, IANA delegates
Regional Internet Registries (RIRs) /8 address blocks (8-bit
network identifiers, also historically called “class A”
address blocks), which the RIRs can then divide into
variable-length blocks for further assignment to ISPs or
other registries [6, 7]. In this regime, the maximum address
block that a site can ever be given is a /8, which leaves only
24 bits for sub netting and addressing within the
organization. Historically, large or complex organizations
have required multiple /8s. For instance, at least 7 /8s
belong to the US Department of Defense. Considering there
are only 256 such blocks, the IPv4 address space can be
seen as severely limited in its ability to provide unique
addresses to the elements of large organizations worldwide.
To compound matters, even using multiple /8s is a poor
solution, since there is no guarantee that the blocks will be
numerically continuous, and if they are not, then both the
local numbering scheme may be awkward, and multiple
global routing table entries will be stored and propagated
for the same site. In recent years, many IPv4 users have
circumvented these issues by using Network Address
Translators (Nat’s), although this practice is known to be
fraught with problems of its own. Unicast address is a one
address on a single interface and also it is delivery to a
The following are types of unicast IPv6 addresses:
Aggregately global unicast addresses. Identified by the
format prefix (FP) of 001, these addresses are equivalent to
public IPv4 addresses. Local-use unicast addresses. Provide
two types of addresses:
(a). Link-local addresses. Identified by the FP of 1111 1110
10, these addresses are
Used by nodes when they are communicating with
neighboring nodes on the same link.
(b). Site-local addresses. Identified by the FP of 1111 1110
11, these addresses are equivalent to the IPv4 private
address space. Use these addresses between nodes that
communicate with other nodes in the same site The
documented policy for the downstream assignment from
RIRs to Local Internet Registries (LIRs) is that each LIR
receive a minimum of a /32, and the minimized address
block that an LIR can then give to a site is a /48 block3.
Since an Ipv6 site can expect at a minimum, a /48, this
allows for 16 bits of sub netting space and 64 bits for
interface identifiers within a subnet (80 bits combined).
Contrast this to an Ipv4 site that can expect a maximum of a
/8 block, leaving only 24 bits of space to be used for sub
netting and host addressing combined. Since in reality, the
vast majority of Ipv4 sites do not get /8s, but rather /16s or
/24s, there are more likely to be only 4 to 8 bits left for
identifying hosts within a subnet, using global addresses.
(c). Loop back address:-This is as address used by a host to
test itself without going into the network. It is used to
identify a loop back interface, which enables a node to send
packets to it. In this case a message is created in the
application layer, sent to the transport layer, and passed to
the network layer. However instead of going to the physical
network, it returns to the transport layer and then passes to
the application layer. The IPv6 loop back address,
0:0:0:0:0:0:0:1 or :: 1, is equivalent to the Ipv4 loop back
address of 127.0.0.1.in Class – A, 127.127.0.0 in Class-B,
127.127.127.0 in Class – C.
The Ipv4 loopback address is an integer type
INADDR_LOOPBACK. The Ipv6 loopback address is
an in6_addr structure defined in <netinet/in.h>. For
The symbolic constant named
IN6ADDR_LOOPBACK_INIT is defined in
<netinet/in.h>. Use it only when declaring a sockaddr_in6
For example: struct in6_addr
A. D. Unspecified address (This host on this network
address):-This is an address in which the prefix part as well
as suffix part are zero. In other words the entire address
consists of zeros. It used only to indicate the absence of an
address, this type of address cannot be assigned to a node.
This type of address is used by a host at bootstrap time
when it does not know its ip address. We can use this type
of address as a source address. The unspecified address
can’t be used as a destination address. The Ipv6 unspecified
address, 0:0:0:0:0:0:0:0 or ::, is equivalent to the Ipv4
unspecified address of 0.0.0.0.
B. E. Concept of Class full v/s Classless addressing: The Ipv4
is broadly divided into Class-A, Class-B, Class-C, Class-D,
and Class-E types, where as Ipv6 Classless is addressing.
C. F. Concept of Netid and Host id:- The Net id is also called
as Prefix part. It is a portion of an IP address that defines a
network. Where as Host id is a portion of an IP address
which identifies a host or router on the network. It is also
called as suffix section. We will use prefix and suffix in
Class-A, Class-B as well as Class-C addresses in Ipv4.The
Netid in Class-A is 8 bits and Hostid is 24 bits, where as in
Class-B the Net id is 16 bits and Host id also 16 bits, and in
Class-C the Netid is 24 bits and Hostid is 8 bits. The netid
and Hostid in Ipv6 are totally different from Ipv4. The first
64 bits address space of an Ipv6 address is considered as
Netid and another 64 bits address space is considered as a
Hostid. The below figure represents a Netid and Hostid in
D. G. Address allocation:- Usually in Ipv4, addresses were
allocated by network class. As address space is depleted,
smaller allocations using Classless Inter-Domain Routing
(CIDR) are made. Allocation has not been balanced among
institutions and nations; where as in Ipv6 Allocation is in
the earliest stages. The Internet Engineering Task Force
(IETF) and Internet Architecture Board (IAB) have
recommended that essentially every organization, home, or
entity be allocated a /48 subnet prefix length. This would
leave 16 bits for the organization to do sub netting. The
address space is large enough to give every person in the
world their own /48 subnet prefix length.
H. Address lifetime : In IPv4 Generally, not an applicable
concept, except for addresses assigned using DHCP, where
as in IPv6 IPv6 addresses have two lifetimes: preferred and
valid, with the preferred lifetime always <= valid. After the
preferred lifetime expires, the address is not to be used as a
source IP address for new connections if an equally.
IPv6 brings major changes to the IP header. IPv6’s header
is far more flexible and contains fewer fields, with the
number of fields dropping from 13 to 8. Fewer header fields
result in a cleaner header format and Quality of Service
(QoS) that was not present in IPv4. IP option fields in
headers have been replaced by a set of optional extensions.
The efficiency of IPv6’s header can be seen by comparing
the address to header size. Even though the IPv6 address is
four times as large as the IPv4 address, the header is only
twice as large. Priority traffic, such as real time audio or
video, can be distinguished from lower priority traffic
through a priority field. The images below show the
difference in the headers. Red designates fields in the IPv4
header that are no longer present in the IPv6 header.

I. Security:- Security is a key feature of IPv6. IPv6 is
primarily focused on improved security, which makes it
popular as data security becomes more and more of a hot
topic in all areas of IT. There are many standardized and
required security features within IPv6 without having to
make changes to applications. Among the improved
security features is packet signing to handle authentication.
Data confidentiality through encryption helps aid security
within IPv6. IPv6 includes an end to end security model
that is designed to protect DHCP, DNS and IPv6 mobility.
While IPv6’s improvement in security does not make IP
invulnerable from attacks, it is certainly a positive and
J. Routing:- The IP routing experience differs with the
implementation of IPv6. Smaller routing tables result in
more efficient routing and less overhead through faster
computation and aggregation. The routing structure makes
use of a hierarchical structure that is also more efficient.
K. Neighbor Discovery:- Neighbor Discovery (ND), as
specified in RFC2461, is an important piece of IPv6
because it replaces Address Resolution Protocol (ARP) and
Internet Control Message Protocol Redirect. ND allows
hosts to find neighboring routers, discover addresses,
address prefixes and additional configuration information.
For routers, ND can be used to broadcast the configuration
parameters for hosts seeking connectivity as well as provide
improved hop and addressing information for its hosts. The
following data structures are defined in RFC2461 on
examples for storing ND related information:
(i). Neighbor Cache: Address information is stored about
individual neighbors that the host has sent traffic to
(ii). Destination Cache: Address information is stored about
destinations that traffic has been sent to recently.
(iii). Prefix List: Prefix lists are defined from information
received from Router
Default Router List: Keeps track of default routers based
from Router Advertisement.
L. Mobility: Due to the way Mobile IPv4 operates (in its
most efficient mode),using triangle routing, and packets
will cross part of their path within a tunnel, and then
another part regularly, with no tunnel. Thus, the IPv4 PCI
size changes depending on where in the network it is
measured when Mobile IPv4 is used. On the other hand,
we will assume a Mobile IPv6 scenario where Route
Optimization (RO) is supported, such that packets go
directly to their destination without tunneling. This is a
feature of IPv6 that has no analogue in IPv4. In a Mobile
IPv6 with RO setting, though, different PCI components get
placed on a packet depending on whether a mobile node
(MN) is using a Care-of Address as a "from" address in
outgoing packets, whether the Care-of Address is being
used as a "to" address by a corresponding node (CN),or
whether Care-of Addresses
directions(between two MNs, both away from their "home"
are used in both
In conclusion, IPv6 offers many potential business case
advantages over IPv4 and is currently possible to use
successfully in production environments with readily
available materials, possibly without even requiring
hardware or software upgrades from currently used
systems. Consumer upgrades are underway, but will take a
long period of time. Consumer products will drive
consumer upgrades. Mobile IP devices, home gaming
systems and other consumer-focused products will begin to
incorporate IPv6, bringing it into the home. IPv6 enables
addressing architectures that scale well in terms of the
number of nodes and sub networks, the size of sub
networks, and the degree of change within sub networks;
including practical cases where IPv4 becomes difficult to
use robustly. Mobile IP devices are already connecting to
802.11 Hot Spots that run IPv6. ISP upgrades to IPv6 will
likely be consumer driven. As some ISP's begin to upgrade
their networks to IPv6, users will see further IPv6
integration in their homes. Without doubt, IPv6 represents a
considerable improvement if compared to the old IPv4
protocol stack. The new suite of protocols provides
innumerable features that improve both the overall
functionality as well as some specific security functions.
Although IPv6 offers better security (larger address space
and the use of encrypted communication), the protocol also
raises new security challenges. Particular aspects of IPv6
that we have positively identified as advances over IPv4
IPv6 implementation and migration cannot and should not
happen overnight. Major changes are required in all areas of
industry to allow migration. Countries and companies, both
large and small, must make the move to IPv6 before overall
migration of the Internet backbones can happen. As
organizations test and complete their migration to IPv6, we
move closer to an IPv6 Internet. Some estimates state that
IPv6 will not be fully implemented until 2030 or as late as
2040. While major steps are being made towards
implementation of the new protocol, a completely IPv6
Internet is many decades away.
