What is the Full Form of IPV6?

IPV6 Stands for “Internet protocol version 6”.

What is IPV6 (Internet Protocol version 6)?

Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4 In December 1998.

WHY WE NEED IPv6 WHEN WE HAD ALREADY IPv4:-

IPv4 uses a 32-bit address for its Internet addresses. That means it can provide support for 2^32 IP addresses in total around 4.29 billion. That may seem like a lot, but all 4.29 billion IP addresses have now been assigned, leading to the address shortage issues we face today.
IPv6 utilizes 128-bit Internet addresses. Therefore, it can support 2^128 Internet addresses—340,282,366,920,938,463,463,374,607,431,768,211,456 of them to be exact. The number of IPv6 addresses is 1028 times larger than the number of IPv4 addresses. So there are more than enough IPv6 addresses to allow for Internet devices to expand for a very long time.
