Using own NS for your domain

Question

I have a dedicated server from 1and1.

Let's say I have a domain named example.com. Can I point it at ns1.example.com and ns2.example.com and use it for other domains?

Note that if you don't register glue records with your registrar, this will form an unresolvable loop. "How do I find the name server for `example.com`?" "Ask `ns1.example.com` or `ns2.example.com`." "Okay, how do I find the IP address for those so I can ask them?" "Ask the nameserver for `example.com`." "That's what I wanted to know in the first place!" — David Schwartz, Mar 18 '12 at 05:39
@DavidSchwartz; I did this before you write it. I went my registar. Create 2 ns with my domain and point it to the IP of my dedicated. If you write it as an answer I could choose as accepted. — borayeris, Mar 19 '12 at 17:29

Yes, but unless you've got another, geographically diverse, server to host the second nameserver, you shouldn't. There are whole RFCs (ie RFC2182) on how DNS should be run; I'd suggest reading them before you embark on this adventure.

Depending on how you host your DNS, you may be opening yourself to DNS cache poisoning, or leaking information you don't want to share (think Active Directory).

I would advise against hosting your own DNS; since you are increasing your surface area of a DOS. Your ISP is probably (hopefully) better than you are at this.

Depending on the situation, you may want to consider a setup similar to this other question.

I logged in my registar and created 2 ns with my domain and point it to the IP of my dedicated. Now it works.
