The registrar of salatti.net is not EuroDNS but Dot Registrar. EuroDNS
is probably just a proxy, which complicates the debugging.

You probably need to register the nameserver, together with its IP
address. This is because, otherwise, there is a chicken-and-egg
problem (to find out the IP address of the name server, you need to
ask the name server...)

Yes, but this requires setting up the "glue records", the IP addresses
of the name servers. This glue is not necessary when the authoritative
name servers are out of the zone.
