IP v4 and IP v6

[Bodhost-Andy]

The Internet Protocol is the protocol by which data is sent from one computer to another on the Internet. Each Host on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. When you send or receive data Any packet is sent first to a gateway computer that understands a small part of the Internet. The gateway computer reads the destination address and forwards the packet to an adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That gateway then forwards the packet directly to the computer whose address is specified.

Because a message is divided into a number of packets, each packet can, if necessary, be sent by a different route across the Internet. Packets can arrive in a different order than the order they were sent in. The Internet Protocol just delivers them. It’s up to another protocol, the Transmission Control Protocol (TCP) to put them back in the right order.

IPv4 :- Internet Protocol version 4 is the fourth iteration of the Internet Protocol (IP) and it is the first version of the protocol to be widely deployed. IPv4 is the dominant network layer protocol on the Interne.IPv4 is 32 bit application.

IPv6 :-The good news is that IPv6 principles are very similar to those of IPv4. Moreover, networks and client applications can make the transition to IPv6 easily. One stumbling block is that we humans struggle to see patterns within these new large hexadecimal numbers. IPv6 is 128 bit application

IPv4 is towards it's end of IP allocation and now proceeding towards IPv6 allocations. They would probably be like <tt class="xph">xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxx x</tt> where x is a hexadecimal digit that represents 4 bits.

You can also use the IPv6Gate to browse IPv4 websites without any configuration changes or without installing any additional software.

The only downside is that the IPs are usually a bit tough to remember as they are longer. So if you struggled to remember the 4 sets of numbers, you'd be in for a shock when IPv6 comes along ;)
