Re: Should a nameserver know about itself?

It is mostly big ISP's that have several nameservers for customers, of which maybe some is also nameserver for their own domain. Telia is a big ISP in Sweden. One of their domains are telia.com. They have several nameservers under telia.com, of which dns3.telia.com, dns4.telia.com, dns5.telia.com and others are not authoritative for telia.com. There are never any problem with that design. In our test of delegation we require that we can get an authoritative answer of the request for an A record of the nameserver name. If the resolver happens to give such an answer we accept that, or we explicitly query the nameservers of the name.
