Ip memoirRecent years saw huge subjoin in net growth there were 40,073 networks on Internet (as of 10/4/94) and it was multiply approximately every 12 months. The current version (IPv4) of Internet protocol was sufficient for 20 years, but if Internet will continue to grow, jolly soon we will run out of addresses for each(prenominal) connections because IPv4 can address only 32 bit addresses (which argon millions of connections). This is the major drawback of IPv4. The other issues is that IPv4 was not designed to handle real time applications such as image and audio efficiently and IPv4 can create a lot of fragmentation due to the lack of ability to predict or detect the bottlenecks in the packets path. The next generation of IP was designed by Internet Engineering Task Force (IETF) to handle all of these problems and was first off presented on July 25, 1994 in Toronto. Thou structurally it is very different from IPv4 it unflurried incorporates all the successful feature s of IPv4 like its ability to adapt to many topologies or technologies at the same time. IPv6 is increasing address format from 32 bits to 128 bits. This increase gave 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses (should be more that the packet since switching the paths for each packet will degrade performance of the network. You (well the protocol) can request the unbreakable path, for the applications successfully carry on high quality video and audio over the net. Another capital advantage of IPv6 is its compatibility with the IPv4. This will make conversion between these two versions painless. Because it doesnt field of study how well a new protocol is if there is nopractical way to transition the current operational systems running IPv4 to the new protocol. Structurally both versions are also different. They have different datagram systems and unlike IPv4, IPv6 does not specify all the possible protocol features, this makes it more adaptable to the users n eeds. The datagram in IPv6 consists of Base Header, Optional Extension Headers, and the Data Area. The Base Header is doubly as large than in IPv4 due to the added extra 96 bits to the each destination and source addresses, but it actually contains less data. It contains VERS for version IPv6, precedency specifies the urgency0 Uncharacterized traffic 1 Filler traffic (e.g., Netnews) 2 Unattended data transfer (e.g., email) 3 (Reserved)
