I have no idea how many, but I imagine there are *alot* of hosts behind a NAT, or router, that would show those same numbers ... The uniqueness is a combination of IP+hostname ... again, as one pointed out with PCBSD, this isn't always necessarily the case, but, IMHO, that is a flaw of PCBSD having all hosts on the same network using the same hostname ... ---- Marc G.
