With all due respect, the problem with postings like this is that it
actually slows down the process of people finding out the truth for
themselves by perpetuating misinformation. It's far better to either do the
research and post accurate information, or avoid posting.

A) The only "root servers" are those that serve the root zone. What you're
referring to are Top Level Domain (TLD) name servers. B) Policies on whether
name server IP records are necessary for domain registration vary by
registry. There is no hard and fast rule. C) "Glue" is a DNS term of art
that refers specifically to IP addresses for servers whose hostnames are IN
the zone they serve. For example, if you have the following NS records:

example.org.	NS	ns1.example.org.
example.org.	NS	ns2.example.org.

Then glue records are _required_ in the ORG TLD name servers. Otherwise
there is no way for anyone to reach your servers.

However, for those situations where the name server hostnames are all out of
zone, it's generally better to avoid putting IP address records for those
hostnames in the parent zone (regardless of what level we're talking about
here) because it makes the administration of the zones/domains much more
difficult.

That's actually exactly the opposite of the truth. If the name servers for
your COM name are in CA, then the IP addresses can be resolved the normal
way (recursively).
