On my home network, I assign my linux desktop a static IP address 
outside of the range that the router gives out to visiting computers.

E.g. cat-in-the-hat is, and the DHCP range is from I do this in order to have the router's port 
forwarding features make ssh accessible to the outside world.

Another option is to use a dynamic DNS service (like dyndns.com) and run 
daemons/cronjobs on each computer to update the dynamic DNS, but I'm 
not sure whether those allow you to map names to the unroutable IP 

P.S. If satan and lucifer are on all the time, then they won't lose 
their DHCP lease, and their IP addresses won't change anyway.
