But yes, the network stack itself is a different question, then again, you can just route a /64 into the loopback device and let your apache listen there... (which also allows you to do easy-failover as you can move that complete /64 to a different box ;)
Funny you should mention that. A couple of tricks I've seen: * instead of a linked list and O(n) searching of interface aliases, use some kind of tree to map local IP -> interface. * hacks to do a "bind to all damned IP addresses and let userspace sort it out". I've done the former for a few thousand aliases with no degredation in performance. The hacks available for freebsd-4.x for the Web Polygraph software did something similar. 2c, Adrian
