IPv6 Address

Each device on the internet needs an IP address. The current version of the Internet Protocol is IPv6, which replaced IPv4, which was limited to fewer than 5 billion variations. IPv4 was in the format many are familiar with: four numbers separated by periods. For example:

In the United States, most mobile phones use an IPv6 address, but only a small percentage of computers do.
