I've been searching around for an answer via google and maybe I don't know the right search terms. So heres what I'm wondering.
I'm running a webserver in my office. Lets say I have
www.example.com with a DNS server registered for ns1.example.com running bind.
Now lets say I want to add
www.anotherexample.com. I know I can just use ns1.example.com for the name server on the domain since I already have the DNS registered and setup. My question is... Can I register another DNS server at the same IP so that I can use ns1.anotherexample.com instead? Sorry if this doesn't make sense....
