Ahh, you want to create a name server with your registrar.  The process 
used to accomplish this task varies from registrar to registrar.  Contact 
yours for their procedure.

Do not use a CNAME as the RDATA for an NS RR.  Use an A RR there, and make 
it match the one you provided to your registrar / parent when you 
registered the name server.

(on a side not, the term DNS is typically reserved as an acronym for the 
term Domain Name System, not Domain Name Server, as I have begun to catch 
on that you are using it in the latter sense.  You will probably confuse 
less people if you use the term name server)

You have asked a many part question here:

A)  If you want the domain name primarydns.com then yes, you must register 
the domain name.  That is to say, if you want to have the right to name 
hosts that end in primarydns.com, then you must own the domain and 
therefore must register the domain with an approved registrar for the com 
domain (of which there are many).  BTW, Internic no longer registers 
domains, however, their site (which I am sure you have visited recently 
during your research of your problems) can direct you to all of the 
approved registrars.

B) If you want to use the fqdn 'dns.primarydns.com' as a name server when 
registering other domains, then that name server must be also registered 
with your registrar.

C)  The relationship between your name server and the domain 
primarydns.com is that your name server would be known as the primary 
master name server for the zone primarydns.com (I am assuming you have 
arranged to have someone else be slave for this zone or you have other 
name servers that will be slave for this zone).  Taking it one step 
further, the domain primarydns.com is a subdomain of the 'com' domain.

A)  On your name server you would have a zone file that contains the zone 
data for the zone primarydns.com.  You can "call" this file anything you 
like.  The name of the file on your local file system is your business and 
has no effect on the operation of the DNS.

B) Quoting the rest of your question "and a cname in it to reflect the dns 
portion" ... leaves me asking, What?



I hope this helps...
