Conflicting glue records?

[Dawn Connelly]

Right, but his question was regarding the host record for the name
server. You tell the registrar the name and IP address of the name
servers that are authoritative for the domain. The registrar then
pushes those glue records to the root servers. Root doesn't care what
the name and/or IP address of the name servers are. They are unrelated
across domains. There isn't any cross domain verification. If you say
that the FQDN and IP address of the authoritative name server is
something, the registrar believes you and tells root. Root believes
the registrar. The registrar and root don't do a lookup on the FQDN of
the name server that is provided- hence it being called a glue record.
You have to manually enter that data. At least that has been the case
with ever registrar I've dealt with.
