IPv6 History and related RFCs

The IPv4 was first developed in the 1970s, and the RFC 791 (IPv4) functionality was published in 1981. Because of the rapid expansion of the internet, IPv4 address space has been getting consumed over the years after 1990's.

Internet Engineering Task Force (IETF) started working on a new protocol from 1994, which is going to replace IPv4.

Following are the major RFCs related with IPv6, which will replace IPv4 in near future.

• The Recommendation for the IP Next Generation Protocol (RFC 1752), was published in 1995.
