[CLUE-Tech] Getting the IP

[Dennis J Perkins]

Actually, I think DHCP came out of bootp.  I think Windows just 
popularized it.

If you know the MAC address of your Ethernet card, you might be able to 
tell DHCP to always assign the same IP address to that card.  That does 
negate much of the advantages of DHCP, but at least you could make 
changes from a central location.  I assume that DNS3 makes this unnecessary.
