What is IPv6?

The Internet is possible due to a large system of addresses not unlike street addresses for the houses in a town. This system is called Internet Protocol or IP for short. Currently, the Internet operates on IP version 4, which supports about 4 billion addresses. As the Internet expands these addresses will be used up making it impossible to add new computers, servers, or mobile devices.

To remedy this, IP version 6 (IPv6) has been carefully designed to allow for 4 billion times 4 billion or 340 undecillion addresses which will ensure that the Internet can’t run out of addresses in any imaginable amount of time.
