Thanks for all the responses so far. My thoughts are pretty much summed up by Mike and Nate, although I would suggest that no one is going out of their way to make these IPs accessible -- rather, they aren't going out of their way to make them inaccessible. Luckily, most websites don't make their stats accessible, or else the problem would be much larger -- anyone could get a list of websites you have ever visited, using a simple google search, like this (to pick a hostname at random from that IETF page): http://www.google.com/search?q=%22tge1lba9.emirates.net.ae%22 While not all IP addresses are linked to individuals, some are, and I think this is mainly a privacy problem for those individuals who have static IPs.
