Thus spake Petri Helenius (pete () he iki fi) [28/08/03 16:23]:
I dont think this would work too well.  The users who are infected 
often think something is wrong because their connection and computer 
are not working quite right. So they disconnect / reconnect / reboot 
so they burn through quite a few dynamic IP addresses along the way.

This is an artifact of ISP?s wanting to have static IP?s as an add-on 
premium service
so they provide short lease times and change IP as often as it?s 
feasible without
interrupting service unneccessarily.

Or potentially an artifact of wanting more IP space from ARIN, as opposed to
assigning a static IP to every user we have, even the ones that are only
connected for about an hour a month.  But hey, that's just a minor detail.
