I think he's talking about a single system that is the SOA for multiple
domains. Plus e-mail! i.e. virtual
If thats the case (see below)... Note that ns1.mydomain-1.com and
ns2.mydomain-1.com are the SOA/NS for both zones. In other words, they are
the name servers that are registered at the TLD's. The MX records for both
zones can be the same or or reference different systems. Adjust the IP's to
fit your network.
