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be able to get access to the modern IPv6 Internet by using a service such as Cloudflare Warp, which works by using your out of date local connection to tunnel traffic via Cloudflare servers.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. Clicking the "test" button next to each site does this automatically.

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

Address Search: You can search for sites by their IPv6 addresses using wildcards. Use * to match any sequence of characters and ? to match a single character. For example, 2001:db8:* will find all sites with IPv6 addresses starting with "2001:db8:".

Exclude IPv6 Sites: You can exclude sites whose names start with "ipv6." by checking the "Exclude sites starting with 'ipv6.'" option. This is useful for filtering out IPv6-specific subdomains for otherwise dual-stacked sites.
