I’m trying to get my MIAB working with a .is domain registered on isnic.is.
They require nameservers to register and pass some tests. One of the tests is that the PTR has to return the full nameserver name, so there should be a PTR record to ns1.box.example.com and another to ns2.box.example.com .
MIAB sets the PTR to box.example.com, without the ns1 and ns2. Is there a way I can modify this so that there are PTR to ns1.box and ns2.box?
