ABOUT IPv6

What is IPv6?

IPv6 is the next-generation Internet protocol that is designated to replace IPv4. First known as Next Generation Internet Protocol (IPng) when it existed as a committee within Internet Engineering Task Force (IETF), now it’s officially known as IPv6 and defined by documents called Request For Comments (RFCs) since 1998. IPv6’s major claim to fame is its 128 bit addresses. That’s 79 billion billion billion times more addresses than IPv4. Well maybe.
