ns

Is it allowed to have an NS record be a CNAME? E.g.:

subdomain.example.com.       IN NS  ns1.example.com.
ns1.example.com.             CNAME  foo.example.com.
foo.example.com.             IN A   10.1.1.1

This doesn't seem to work in bind though this (of course) does:

subdomain.example.com.       IN NS  foo.example.com.
foo.example.com.             IN A   10.1.1.1

Any pointers to RFCs prohibiting this setup would be appreciated.

This is bit of a theological question, but nonetheless... So, a server has a hostname, let's say the fqdn is hostname.example.com (to be really precise about what I mean, this is the name that is set in /etc/sysconfig/network). The very same server has multiple interfaces on different subnets. Let's… >>> More
