Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

Reading a book and it states that you should not register nameserver names such as for the domain as you'll create a catch-22 situation when looking up etc. I know what a catch-22 is, but I just don't see how this fits in.

At which stage does this occur exactly, when internet central directory queries whois records for that domain to find nameserver ip ?

excerpt from "The difinitive guide to CentOS (APress)"

Caution As you can imagine, telling the world that the primary DNS server for is dns0. has some issues. Mainly, this has you running around in circles because you’ve created a catch-22 situation. You cannot look up because to do so you need to ask dns0. Now, as long as you have name servers in another domain, this will still work, but it’s clearly a bad idea. Stay away from this one, and if you have to, use a so-called glue record that defines in the parent .org zone to solve the issue.

I find this very odd, what book was it from? The nameservers for are, and That sort of thing is fairly standard practice (Even Google do it). Unless I've miss-understood the question –  sam Nov 30 '11 at 11:04

funny book. clearly most of domains are set this way. Glue records is not some cheap workaround, that is how DNS designed to work. –  Sandman4 Nov 30 '11 at 13:52
Btw, it's NS records, have little to do with WHOIS –  Sandman4 Nov 30 '11 at 13:53

It's simply not true to say that doesn't work, or causes problems. For example, on my main domain:

[madhatta@www tmp]$ whois
[Redirected to]
 Domain servers in listed order:

which works just fine. The technical elements that makes this work are the glue records, which you can read about at the link above, and elsewhere.

I'd go further than that: Not only is it not true to say that it is bad practice, it is a good practice that one should adopt. –  JdeBP Jan 19 '12 at 18:05
