This leads to the question. Which method has less overhead (ie
greater speed). I currently have 128 dummy interfaces hard coded into
the kernel (modules take more RAM). I am using about 80 of them for
WWW servers on one machine. It works GREAT :). If IP_ALIASING can
shave a few ns/ms off the connection I would do it.

BTW, I'm running Apache and I configure all interfaces on bootup. I
have a 7 bit subnet routed to the machine. The machine is on
204.97.12.0 net for its real interface and all the dummies are on
205.246.242.0/25. Things seem to work very well. The machine is a
bit overloaded but I have anotherone I'm bring online this week.

Currently using linux-1.2.13 + the unoff .14 patch kit.
