while most ISPs distribute the ips by region*, there's no guarantee that a particular IP range would be in a particular region. Especially given ISPs own the blocks of IPs and a given region might have many ISPs (cable, dsl, dial-up, etc..) and thusly many different IPs in the region. Now that I think of it, the major dial-up outfits are a good example of large roving ip blocks as I severly doubt they keep IPs by region
*the couple I knew the ip ranges for (cox and comcast) do, but they might be exceptions (cox owns 68.x, comcast owns 24.x) |
