I wrote a script that aliased several thousand IPs to various interfaces. I didn't see any problem. (more mbuf clusters were allocated and used) To alias more than a couple hundred takes a good bit of time, so consider that to be the factor in how many you put on a machine. I don't want to wait 20 minutes while the box adds aliases. :) I guess the correct answer to your question is "enough". Have a good one. | Matthew N.
