If they really are using on ISP that has multiple ranges, just look up the reverse DNS, and it should resolve to the same ISP. Even if it isn't, how can you be sure they don't just have two ISPs? I remember that when we still had dial-up, we had two ISPs, one was a bit faster, but wouldn't disconnect as much, especially if only receiving a small amount of traffic (like talking on IRC, or possibly (guessing, since I didn't play Graal till I got broadband) idling in a slow traffic level on Graal, just PM'ing). The other one rarely disconnected, but was about 5-10k slower. Of course, they might just be using it at school, or their other parents house (if their parents are seperated). But is it really up to the server staff to decide, shouldn't they just point it out to Stefan and let him deal with it? In then end it would just be handy for server staff to be able to set good IP bans, or possibly RC rights.
