 That is interesting because on my home network all machines get the same
 address no matter in which order they are turned on.

Does it continue to do so if the DHCP server is restarted? I imagine
it's probably an implementation detail - whenever possible, try to
assign a given MAC address the same IP it had previously. My DSL router
does this, but may allocate different IPs after being restarted.

Thanks everybody!  I looked into my router's software capabilities and
set it up so that the MAC address on the server is always assigned the
same number.  Works like a charm.

I know this was a little off topic - but do appreciate the pointers.

 I would like to say connect to MyServer and have it find out the IP
 address in the router.  I have DHCP turned on in the router, but I
 think I need to set up NetworkManager to use a dhclient.  Is that what
 I want to do?  Can anyone point me in the right direction?

NM should already use DHCP by default.  You can either set up each
machine to have a static IP address, or sometimes the Linksys can do
Static DHCP where it assigns the same IP address each time based on
the MAC address of the machine.  That's probably in the management
interface somewhere; try poking around.

Because the DHCP server implementors are free to cache the MAC - IP
leasing even when said MAC isn't active.
