Ok, I'll bite... I find the idea that an ISP must publish customer information offensive. There is no reason why a guy who wants to get a T-1 into his house and a /24 to support all the stuff he's doing at home should be forced to publish his full name and home address to the world (or worse, should have that information published to the world by his ISP without his knowledge). Didn't we already have this discussion back when it was about static /32s, /29s, and the like? And didn't those people get to keep their privacy? You can always track down the actual registrant and talk to them if you have a problem, and as has already been pointed out, they're a lot more likely to respond than the person listed in the assignment record. Believing that the "spam problem" would be solved if only the source IP addresses of the spam could be tracked to a physical address is a fallacy anyway. Matthew Kaufman matthew@eeph.com Ps. The legitimate business reason of trying to keep your customer list private so your competitors don't spend all day calling your customers should apply too, but I'm a lot less worried about that than the simple privacy issues for the end users.
