Anyways, the question is still valid: how many IP aliases we can reach in
an OpenBSD system? which is the limit?
in theory, there is none but memory.
in practice, it is a simple linked list, so things get slower at some
point.
Many moons ago, I looped over creating tun-devices adding the increasing
ip 10.x.y.z to each to see how many devices one could have, and it went
as far as 26k interfaces before bombing out, so that number (or many
more than that by now) is definately possible when just giving each
interface one address. Testing how many aliases one interface can hold
shouldn't take very long either.
