IPv6
Sign in to saveInternet 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, and was intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017.
AI overview
IPv6 is the latest version of the Internet Protocol, the fundamental system that identifies computers on networks and directs internet traffic. It was created to solve the problem of running out of unique addresses available under the older IPv4 system.

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, and was intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017.
Devices on the Internet are assigned a unique IP address for identification and location definition. With the rapid growth of the Internet after commercialization in the 1990s, it became evident that far more addresses would be needed to connect devices than the 4 billion (232) addresses IPv4 made available. By 1998, the IETF had formalized the successor protocol, IPv6. This uses 128-bit addresses, yielding an address space of 2128, 1038, or 340 undecillion total addresses. Several transition mechanisms have been devised to allow IPv4 and IPv6 to interoperate, but IPv6 is not backwards-compatible with IPv4 and the two do not interoperate directly.
