IPv6 address

IPv6 is intended to replace IPv4.
IPv6 uses a 128-bit address, theoretically allowing 2128, or approximately 3.41038 addresses.
The total number of possible IPv6 addresses is more than 7.91028 times as many as IPv4, which uses 32-bit addresses and provides approximately 4.3 billion addresses. The two protocols are not designed to be interoperable, complicating the transition to IPv6. However, several IPv6 transition mechanisms have been devised to permit communication between IPv4 and IPv6 hosts.

Compatibility test

This website has been developed to test your compatibility with the IPv6 protocol.
If the test is successful, it means that you are fully capable of exchanging information correctly with a server in IPv6.
Some users who can connect to IPv6 addresses, however, have problems when both types of addresses are registered for the same domain name. The test takes into account these two elements.
