> So you're saying that business networks typically have completely random IPs setup by their ISP? No. If 3taps was using a static IP address to access Craigslist, then IP address is at least somewhat meaningful as evidence, but mostly Internet users do not have static IP addresses and mostly only organizations that want to operate Internet servers, or Web servers, do. Why? Because mostly to get to a server, a user uses a domain name which uses the domain name system (DNS) which requires a static IP address. Yes, in the specific case 3taps asked for trouble and got it. But the article seems to suggest that this case is a threat to ordinary Internet users who, maybe, get an unusually large number of Web pages from a Web site. So, there is also some interest in the more general situation. There IP address is poor evidence. To me, in the general case, say, Web sites that send data to anonymous users, without strong authentication, etc., should just f'get about the lawyers, suck it up, and f'get about users downloading data. Else the Web site can use strong authentication of users, charge for access to the site, etc.
