I'm sure that is true.
But where does the machine keep the old IP?
I couldn't find it anywhere.

Actually, I have solved my problems now.
The basic problem was that as far as I can see dhcp or dhcpd
was not running properly, if at all, on my Linksys router
(running the original Linksys software).

When I started running dhcpd on my server instead
(and stopped it on the router),
everything started to work as I expected,
and my laptop got its correct address at last.
