Because the IP's are bound to an existing interface, rather than having an
interface all to themselves. If you don't like the term virtual, feel free
to substitute "IP alias" instead. Anyway, who could afford to put 250 NIC
cards into a single box, even if you had the slots for it? :)
The box is set up to bind a seperate server to each IP address, and to
spawn various processes as if each IP address were running on a seperate
machine. It works, except for the fact that tftp uses the "real" interface
instead of the IP address of the parent process. (sigh)
