INTRODUCTION
3|Page
The IPV6 is the next generation protocol for the internet. It has many
advantages over IPV4 .Both are define in network layer protocol. The main
problem of IPV4 is address depletion. To overcome this problem we need more
address space helps IPV6 is 128 bot long which is 4 time greater than IPV4 .
IPv6 provides other technical benefits in addition to a larger addressing space.
In particular, it permits hierarchical address allocation methods that facilitate
route aggregation across the Internet, and thus limit the expansion of routing
tables. The use of multicast addressing is expanded and simplified, and provides
additional optimization for the delivery of services. Device mobility, security,
and configuration aspects have been considered in the design of the protocol.
IPv6 addresses are represented as eight groups of four hexadecimal digits each,
separated by colons. The full representation may be shortened; for example,
2001:0db8:0000:0000:0000:8a2e:0370:7334 becomes
2001:db8::8a2e:370:7334.
ADVANTAGED OF IPv6
1) Real-time Data Transmission : Real-time data transmission refers to the
process of transmitting data in a very fast manner or immediately
4|Page
2) IPv6 supports authentication: Verifying that the data received by the
receiver from the sender is exactly what the sender sent and came through
the sender only not from any third party
3) IPv6 performs Encryption: Ipv6 can encrypt the message at network
layer even if the protocols of application layer at user level didn’t encrypt
the message which is a major advantage as it takes care of encryption.
4) Faster processing at Router: Routers are able to process data packets of
Ipv6 much faster due to smaller Base header of fixed size – 40 bytes
which helps in decreasing processing time resulting in more efficient
packet transmission.
Disadvantages of IPV6
1) Conversion: IPV4 is still widely used and the world is slow to convert to
IPV6.
2) Communication: IPV4 and IPV6 machines cannot communicate directly
each other, in the very rare circumstances that they would need to.
3) Transition: The process of making the switch to IPV6 from IPV4 is slow.
4) Readability: Understanding IPV6 subnetting can be difficult in its own,
let alone trying to remember/memorize your IPV6 address.
APPLICATION
1) Application Innovation of IPv6 in Public Security System
2) Application of IPv6 in Education System
3) Application of IPv6 in Home Networks
5|Page
4) Application in the Financial Industry
FEATURE OF IPV6
1) Large address space compare to IPv4 2)
Simplified headers.
3) End to end connectivity. 4)
Auto configuration.
5) Faster forwarding
EXAMPLE OF IPv6
The following are examples of valid IPv6 (normal) addresses:
2001:db8:3333:4444:5555:6666:7777:8888
2001:db8:3333:4444:CCCC:DDDD:EEEE:FFFF
:: (implies all 8 segments are zero)d
2001:db8:: (implies that the last six segments are zero)
TYPES OF IPV6
In IPv6, three types of network addresses are defined. They are:
1) Unicast address
2) Multicast address
6|Page
3) Anycast address
1) Unicast address
A unicast address identifies a single network interface in a network node.
Network packets are sent to the unicast address to be sent to that particular
interface.
2) Multicast address
Multicast address identifies a group of interfaces on single or different network
nodes. Network packets are sent to the multicast address to be sent cross all the
members of that multicast group
3) Anycast address
Anycast address identifies a group of interfaces on single or different nodes.
Network packets are sent to an anycast address to be sent to an anycast group
member, which is physically closest to the host

IPV6 PACKET FORMAT
1) Version:-The contents of this 4 bit field defines the version of IP such
IPv4 or IPV6. If VER = 6, then the version is IPv6.
2) Priority:-This 4 bit field contents defines the priority of the packet which
is important in connection with the traffic congestion.
3) Flow Label:-It is a 24 bit (3 bytes) field which is supposed to provide a
special handling for a particular flow of data.
4) Playload Length:-The contents of the 16 bit or 2 byte length field are
used to indicate the total length of the IP datagram excluding the base
header.
5) Next Header:-It is an 8 bit field which defines the header which flows
the base header in the datagram.
6) Hop Limit:-Contents of this 8 bit (1 byte) field have the same function as
TTL (time to live) in IPv4.
7) Source Address:-It is a 16 byte (128 bit) internet address which
corresponds to the originator or source which has produced the datagram.
8) Destination Address:-This is a 16 byte (128 bit) internet address which
corresponds to the address of the final destination of datagram.

9)Playload:-The meaning and format of payload field in IPv6 is different
as compared to payload field in IPv4.
CONCLUSION
IPv6 overcomes many of the limitations of IPv4 while introducting new features
and functionality to make the job of the network administrator easier.
Remember that Ipv6 only makes a difference at the network layer of the
networking stack. Many connectivity and security elements, especially in cloud
native applications, are handled at higher layers and are therefore not affected.
So therefore, I understand when the IPV6 is used.
