Jack,

If you never connect to the Internet, you can use anything you want for a domain name. The default, you'll note, is "my.domain" which is not usable on the Internet.

Leaving the Internet OUT of the discussion for the moment:

Domain names are, however, tied to DNS -- domain name resolution to IP address. Some applications will attempt to resolve your fully qualified name, such as bilbo.shire.middle-earth. If that name is not provisioned in a DNS server (and you may have one, Internet or not) you must use file based resolving -- the /etc/hosts file.

On the Internet:

If your OpenBSD platform is publicly exposed to the Internet -- you can use the domain name that resolves to that IP address.

If your OpenBSD platform has an indirect connection, such as on a private IP network, you can use /etc/hosts or your own DNS servers to resolve bilbo.shire.middle-earth.
