Dynamic DNS is a setup primarily for networks with DHCP. Using DHCP, you can
only have 1 IP lease per physical interface. This IP, along with the
system's hostname, are registered in DNS, and that's were we resolve the
names you currently use in a Netbios/WINS environment.

What I said, though, is not entirely true. I could of course add interfaces
with different MAC addresses, which would be considered spoofing, and thus
lease more IP's and register more DNS records.

Or I create interface aliases with static IPs and configure a static IN A
record.

I could also use a multi-homed box with several NICs, thus lease more IPs,
thus registering more DNS records.

In all these setups, I also could run several instances of smbd/nmbd, each
bound to one interface (or one IP, if you will).

Kind regards,
