yeah, someone needs to tell the registry the nameservers that's it,
nobody expect something work out of the blue
otherwise it will not work at all x RFC SOA refresh 24H
no idea what that means, but it makes no sense
In all case a sec. srv. on the same net
no *not* on the same net
thelounge.net. 86400 IN NS ns1.thelounge.net.
thelounge.net. 86400 IN NS ns2.thelounge.net.
ns1 = 85.124.176.242
ns2 = 91.118.73.16
in fact ns2 is the master, ns1 is the salve for historical reasons, both
hosting some hundret domains, both operated at my own for 12 years now
in fact both are even on the same *redundant* cluster
and the whole backends and automation is homegrown

I just wanted to comment that there is no "requirement" to run a
secondary DNS server. It's certainly best practice and should be
considered. However, the goal of having two DNS servers is to promote
redundancy if DNS fails but other services you need have not
this is *not* true at all

Requirements for Name Servers
These tests are performed for the set of NS records and any associated
IP addresses for those name servers. For each individual hostname, tests
are performed against each IP address and protocol pair.
Minimum number of name servers
There must be at least two NS records listed in a delegation, and the
hosts must not resolve to the same IP address.
