Earlier today I changed the IPv6 address used for the LUV server. I didn't keep the old address working because almost no-one uses IPv6 and IPv6 clients can generally fall back to IPv4 if necessary, so the time that the old address remains in DNS caches shouldn't be a problem. Hetzner had decided to remove the address range they had assigned to that server and I had to apply for a new /64.
IPv6 generally won't fall back to IPv4 unless it gets a positive failure for the IPv6. Which could take some time if the IPv6 address is not responding. Having said that, looks like it is working fine for me - and I am using IPv6. -- Brian May <brian@linuxpenguins.xyz> https://linuxpenguins.xyz/brian/
