Ip HistoryRecent years saw huge sum up in Internet growth thither were 40,073 networks on Internet (as of 10/4/94) and it was doubling approximately e really 12 months. The current form (IPv4) of Internet Protocol was sufficient for 20 years, but if Internet impart continue to grow, pretty soon we will run out of addresses for severally(prenominal) connections because IPv4 can wish only 32 bit addresses (which are millions of connections). This is the study drawback of IPv4. The other issues is that IPv4 was not designed to handle real time applications such(prenominal) as video 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 presented on July 25, 1994 in Toronto. Thou structurally it is very different from IPv4 it still incorporates all the successful features of IPv4 like its ability to vary to many topologies or technologies at the same time. IPv6 is increasing address data formatting 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 splinterproof path, for the applications successfully transmit high quality video and audio oer the net. Another great advantage of IPv6 is its compatibility with the IPv4. This will make transition amidst these two versions pain slight. Because it doesnt matter 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 needs. The datagram in IPv6 consists of bagful Header, Optional Extension Headers, and the Data Area. The Base Header is twice as large than in IPv4 due to the added excess 96 bits to the each destination and source addresses, but it actually contains less data. It contains VERS for version IPv6, PRIORITY specifies the urgency0 Uncharacterized traffic 1 filler traffic (e.g., Netnews) 2 Unattended data transfer (e.g., email) 3 (Reserved)
