Hi, I can highly recommend https://ip6.biz/ by Zotan (may or may not be on this list), even though its style more closely resembles https://ipv6-test.com/ . It is also open source, so could be hosted by others if the license is not too incompatible: https://git.ztn.sh/zotan/ip6.biz Thanks Max On 05 October, 2025 10:41 CEST, Geert Jan de Groot via ipv6-wg <ipv6-wg@ripe.net> wrote: Hi folks, In past years, I have used https://test-ipv6.com/ as a quick "sanity test" when connecting to a network, using a guest network, or to check network configuration after making changes. I found it very useful for quick tests. Unfortunately, jfesler is announcing sunsetting the project, see https://retire.test-ipv6.com/. In the FAQ, it is mentioned "Q: Will I (jfesler) transfer the domain? A: I’d consider a reputable RIR or NIC organization serving the public interest taking things over." I wonder if a RIR or NIC organisation would consider taking over to run the service. I think it is too useful to just disappear, there are still too many not-quite-IPv6 networks, and personally I hope I don't lose the service. Thoughts, anyone?
