Servers don't care whether a domain has been delegated to them.  Delegation
is used by other servers to find the server, but a server will respond
authoritatively for any zone that it's configured as a master or slave for.

Think of registration as analogous to a listing in a phone directory.  The
directory lets people find you by name, but even if you're not listed in a
directory, the phone will answer the same way if someone dials its number.

You could use these "stealth secondaries" on your LAN by configuring your
workstations to point their queries to them.  They'll return lookups in
stefan.com out of their authoritative data, and look up anything else by
using the root servers or forwarders.
