The IPv6 standard was approved in 1998 and was designed to replace the IPv4 standard.

There are only a limited number of IP addresses available worldwide. One of the reasons for the new IPv6 standard was now a far higher number of IP addresses available. You could also say that you could now assign an IPv6 address to almost every grain of sand on a beach.

Another motivation for the IPv6 standard is an end-to-end relationship. Manufacturers are required to change the IPv6 addresses of devices once a day after the IPv6 privacy extensions ([link](https://www.internetsociety.org/blog/2014/12/ipv6-privacy-addresses-provide-protection-against-surveillance-and-tracking/)).
