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:
74.6.143.25
An IPv6 address will consists of eight strings of four hexadecimal digits [0-9, and A-F] - each divided by a colon. But leading zeroes, or strings of all zeros are omitted. So, an example of a IPv6 address would be:
2001:4998:124:1507::f000
