My servers should now be dual stack, finally supporting IPv6 next to IPv4. Nothing broke, weirdly. All tests, e.g. with testmyipv6(.com) succeed.

Soon I'm going to have to make some servers IPv6-only, since the old addresses start to cost money. That should break things I guess. The average ActivityPub server will not be IPv6 ready I suspect. It seems DNS64/NAT64 is too expensive to enable, so if it is too much of a problem I'm going to have to run a forward proxy.

Yeah, way too many instances are IPv4 only, especially the ones hosted by a provider. The big ones, and the ones with a tech background, tend to support IPv6.
