Well, I can argue that some Canadian cable modems do follow different patterns. Although GT are absolutely terrible at maintaining their network assignments, I know for a fact that chunks of both GROUPTELECOM-BLK-5A and GROUPTELECOM-BLK-6A are assigned to operating cable modems. I'm also fairly certain that when the cable provider I refer to finally gets their own assignment from ARIN that it won't likely be from 24/8 (though it might -- it's anyone's guess at this point since I don't the application has even been made yet). Then of course there's NETBLK-GTE-CABLE-DUKE-ADSL. Is that an oxymoron, or just an example of a contradiction to your argument? Making assumptions about the type of last-mile connection in use by some IP address based solely on its classical prefix (eg. 24/0) is just never going to be accurate. Making assumptions about where a classical prefix is routed geographically is going to get you in real trouble. From what I can see 24/8 can be found on many continents, never mind in many countries. -- Greg A.
