IPv6-only Website List

The following sites are only reachable via IPv6.
If you have a legacy connection which is not IPv6 capable, all of the sites below will fail to load.
Due to deficiencies in all current browsers, attempting to load IPv6-only websites from a legacy connection will display a generic error message such as "NXDOMAIN" or "host not found" which gives no clue as to what the problem is.
You can test your connectivity at a variety of sites such as https://ip6.biz a modern connection will show "IPv6: Supported" in green.
If you do not have IPv6 connectivity you should check the configuration of your device and/or router, or contact your ISP.
If you're unfortunate enough to only have legacy connectivity, you may be able to get access to the modern IPv6 Internet by using a service such as Cloudflare Warp, which works by using your out of date local connection to tunnel traffic via Cloudflare servers.
You can also use a website availability check such as https://testmyconnection.net to verify that the below sites are online. Simply copy the URL and check.

Note: Sites listed below with neither HTTP nor HTTPS are still IPv6 only, but are used for something other than web hosting.
