Not.  A significant portion (I'd guess a vast majority) of the
machines out there have either dynamically allocated IP
addresses or are behind a proxy or NAT firewall.   Even if that
weren't true, you'd be keeping track of computers, not of
people.  I assume it's the latter that matter to you?

Because it's going to be wrong most of the time?
