IPv4/IPv6 test page

This is a test page to see whether a client can connect over IPv4 or over IPv6, and what it prefers.

The main page is on a dual-stacked server, you are using legacy IP and your address is: 216.73.216.107 ((none))

The server address you have reached is: 195.30.8.34

NOTE: You are using SSL, so the literal-address iframes might throw cert warnings - the whole IPv4/IPv6 certificate bit at LetsEncrypt is very new, uses shortlived certs (6 days) and my toolchain is not working perfectly yet (renewals might be missed).

You can use the non-SSL site to check for NAT64/464XLAT setups (which need literal-address tests)
