If the IPv6 only test shows "Server not found" or similar error or search page then you do not have working IPv6 connectivity. "Normal Test" shows which protocol your browser preferrs when you have both IPv4 and IPv6 connectivity.



You can access this page with any of these easy to remember url's:



ip4.me - IPv4 only test

ip6.me - IPv6 test with IPv4 fallback

ip6only.me - IPv6 only test

whatismyv6.com - IPv6 test with IPv4 fallback



For automated queries use /api/ on any of the urls for a simple plain text csv result that will not be affected by future html changes on the main page. Recommended API urls

(Don't forget the trailing slash to avoid unnessary 301 redirects):



ip4only.me/api/ - IPv4 only test

ip6.me/api/ - IPv6 test with IPv4 fallback

ip6only.me/api/ - IPv6 only test



Some day far in the future ip4.me may have a AAAA record so it is not recommended for "IPv4 only" automated queries. Use ip4only.me instead.
