Wow. Thanks for all your help.
The MAC address -- ah, ok. So I would have to replace the network card like
you said. Someone else mentioned that earlier, too. Now it makes sense. So
if I had an extra network card, switching out network cards would work, but
only once since both network cards would keep their ip addresses for the
terms of the leases.
Now that I understand, this means that after the term of the lease my ip
address will be up for grabs and there's a chance that I could get it or
someone else could it back, since the ip address that is on stored in the
ip table(s) is not the one that is actually associated with the mac address
in my network card. When it's lease runs out, the dhcp server will see that
it's not being used and might give it to someone else. Actually, unless
there's something else to all this, I will almost certainly lose it,
because my network card isn't using dhcp anymore. So how would it get
renewed? It wouldn't, right? It will remain on my system, since I entered
it manually, but the dhcp server wouldn't renew it, because my network card
isn't using dhcp anymore. So if it *happened* to be reassigned to someone
else, there would be a conflict. If wasn't reassigned, by chance, my
connection would continue to work as long as that ip was never assigned.
But someday it would be, so it would just be a matter of time until my
connection would no longer work, because it would never be renewed via
dhcp, since my network card isn't using dhcp now.
Sighs... so I'd have to check back periodically, by using "host <ip
number>" to see if I still have the lease. When I don't, then I would need
to turned dhcp back on my network card. Does that sound right, or is there
an easier way? Maybe I should try and swap out a network card from another
computer laying around, and get that one going with dhcp, and then just
leave everything alone?

Yeah it sounds like it was tied to the MAC address instead of either
Netbios naming or the DHCP lease request itself.

There is ALWAYS a chancee that you'll loose the IP, especially if there
is a shortage of addresses available.
However even after 5 days, your IP is thrown to the bottom of the pool
(heh, analogy not intended). Other available IP's are distributed first
on a time bases. That is, the leases that expired long ago get first
priority for re-allocation.
So it's quite possible for your system to be disconnected for months,
and get it's old IP back upon rejoining the network if there are plenty
of IP's available for new systems.
