I know 210/8 & 211/8 are APNIC, I likes to know stuff like : 210.100/16 is Korea and 210.120/16 is China, etc. Does anyone have a : list I can pull from? Maybe I'm going to have a case of stick-foot-in-mouth disease so: <setenv flameproof_panties=ON> :-) This only works for a certain percentage of networks. Most likely a higher percentage post tech bubble collapse. I used to work for a company that had 22.214.171.124/17 and we announced that globally. So you couldn't say 126.96.36.199/17 was in the US (or even NA) as it'd appear from ARIN or other data sources.
I think the right answer is "There is no location information in an IP address for the reason given, and for additional reasons (such as "tunneling", and various mobility schemes). Telephone numbers, particularly North American Numbering Plan Area numbers, do no contain the location information they used to. You can make statistical estimates (the odds are numbers in range X-Y are in area Z).
