What is IPv6’s history?

                           Standardized in 1996, IPv6 was developed as the next-generation Internet Protocol. One of its main
goals was to massively increase the number of IP addresses available. The first production allocations
were made to ISPs and other network operators in 1999, and by June 2006, IPv6 was successful enough
that important test networks shut down. They were no longer needed.Over the past year, major content providers and access networks have started offering IPv6 services to ordinary Internet users. Because IPv6 is so much larger than IPv4, it should last us considerably longer than the 30 years IPv4 has given us so far. But just how large is IPv6?
IPv6 is significantly bigger than IPv4. Compared to IPv4’s 32-bit address space of four billion addresses, IPv6 has a 128-bit address space, which is 340 undecillion addresses. That’s not a number you hear every day! Using IPv6, ISPs generally assign many thousands of network segments, called a /64, to a single subscriber connection used in places such as a home, classroom, or business. Giving every person on Earth a connection with a /64 would barely dent the available IPv6 address space. In fact, while the
Earth’s orbit around the Sun is only big enough to contain 3,262 Earths put side by side, it would take
21,587,961,064,546 Earths to use all the addresses in the part of the IPv6 space we now use.
