Research the IPv4 ns the IPv6 protocols, then prepare a report that explains the likes and
differences of the two protocols and include how and why the transition from IPv4 to IPv6 is to
occur.
Project report body must have 5 pages or more, with Times New Roman12 pt. print double
spaced. Also include a Cover sheet and a Reference page.

Introductory lines:
The internet protocol or IP specifies and describes the technical details and formats of fragments
of data (Also known as packets.) along with addressing schemes (numerical; actually in binary
but can be interpreted as decimals or hexadecimals assigned to each of the devices connected
through the network) in order to uniquely identify them and create a platform for secure and
reliable communication.
Ipv4 over the years was proved and deployed for communications over the internet. However in
the current days it becomes obsolete and deficient in order to serve the huge and increasing
number of users or network devices.
To make this possible, the IPv6 comes into existence. The IPv6 provides many extra features and
claims to support and serve this increasing number of devices for upcoming coming centuries.
Let’s discuss about the similar and distinct features of both IPv4 and IPv6.
IPv4 in terms of IP addresses, Address allocation, masks and types:
IPv6 in terms of IP addresses, Address allocation, masks and types:
IPv4 in terms of IP header:
Headers in IPv4 are of variable length that varies from 20 to 60 bytes.
IPv4 does not identify packet flow for QOS handling.
It adds checksum filed for identification of transmission errors in the data.
IPv6 in terms of IP header:
Uses fixed length of 40 bytes of headers and there is no concept of option filed in header.
It supports packet flow for QOS by flow level filed.
IPv6 does not implements checksum for error handling.
IPv4 in terms of IP packets ports and security:
IPv4 supports the packet size of 576 bytes.
They also support packet filtering mechanisms through firewalls.
IPv4 supports for port spaces of the range 1 to 65535
IPsec in IPv4 is optional.
IPv6 in terms of IP packets ports and security:
IPv6 supports the packet size of 1280 bytes.
They does not supports packet filtering mechanisms.
The way the portts work both in IPv4 and IPv6 are the same.
IPv6 has inbuilt IPsec support.
IPv4 was successful;;y deployed in 1981 over internet whereas IPv6 was planned to be deployed
from 1999 but could partially deployed till the date.
Why transition from IPv4 to IPv6 must occur ?
The deficiency of IP address of IPv4 type is one of the most eye catching reasons for transition
towards IPv6. Each and every day the Internet is experiencing phenomenal increase of devices
which are being connected and using the internet.
In order to provide services to all the address space of IPv4 seems to be fewer. Hence
a transition from IPv4 to IPv6 is must needed to satisfy such demand of larger address space.
Except this, the other technical features like improve.

and simplicity are the major disadvantages can be availed after the transition.
