Well, you can have more than one nameserver!

No, you might run another primary that gets updates from your registrar.  Or
you might run something like split DNS; one internal and one external and
then you simply add your nameserver to the list of NS entries at your
registrar.

You would not want to update your whois record for your Internet Account if
it is dynamic, even if you have two nameservers.

It's best practice to have multiple slave DNS servers (which can pull zone
records from one master) that are located in multiple geographic areas.

If I were you, I would not try to configure and run bind there with Qmail,
due to the nature of learning curve with both DNS and bind, and the
dependent nature of mail to DNS.

Most of what you need to do is going to be possible via /etc/hosts entries.

But if you insist, you can run an additional DNS name server configured for
your IP.
