Adding hosts should work normally.
When you choose the domain for your host, be careful:
If you add an own domain (not just a host), your nameserver address must be IP v6, which can be achieved in 2 ways:
+-------------------+--------------+----------------------------+ | Well-Known Prefix | IPv4 address | IPv4-Embedded IPv6 address | +-------------------+--------------+----------------------------+ | 64:ff9b::/96 | 192.0.2.33 | 64:ff9b::192.0.2.33 | +-------------------+--------------+----------------------------+ (taken from RFC 6052, section 2.4) NOTE: due to changes in tayga, this does not work any more since we moved to a new VM host at 2021-11-06. An immediate fix is possible if you can enter a valid public IP v6 of your DNS server. If that is not possible, make sure your DNS server has a valid A record at least, so it can be referred to by FQDN. With that and a fix to the nsupdate.info code, we can make it working later again based on the FQDN of your nameserver.
We require IPv6 because the machine that runs this service only has v6 connectivity.
Updates to external IPv6 DNS servers should work now, see: issue #140
