Experiment ... go to a college dorm that's wired, plug your laptop or PC in, start using the net.
Nine times out of ten you wont' be challenged and you'll be allowed to use the network.
Has it been a while since you've been on a resnet? They're bad, but most all "ResNet's" I know of are now implementing some sort of MAC/DHCP combo at the very least. That might have been true a couple years ago but recent DMCA notices and Worm activity have /forced/ (often by their upstream) ResNet's to clean up their act. I don't think our ResNet is a shining example of excellence by any stretch but they know who is registered behind each port/ip/mac address which gives you a pretty good idea of who is on your network. I won't comment on what leaves the ResNet on port 25 and what leaves the network with no prayer of ever routing back. *cough* That's a whole 'nother issue for them to deal with, and at some point soon, I think they will. -davidu (speaking only for himself) ---------------------------------------------------- David A.
