> If your ISP isn't keeping track of which customer is using which IP addresses and handling complaints sent to their abuse To be clear, I am the only person (so far as I know) who has the ability to do this. Subscribers are ordinarily segmented by VLAN and the DHCP server hands out a single, predefined IP address on a /30. If a subscriber moves between apartments, their IP goes with them (the VLAN is simply relocated to the new physical port in the new apartment). Which customer has which IP in which apartment is all documented in their customer management system. What they've permitted me to do, as part of testing, is to manually assign myself an IP by removing the VLAN and DHCP restriction on my specific port. If I try to this same stunt in a friend's apartment, on the same ISP, it does not work.
