It is not correct to distinguish google version by ip. I search at google.com and google.fr both from the same ip (show on firefox), but result is big different. how many google version can you see? 1 type different domain(.com .fr etc..) 2 use proxy to similuate different ip 3 Interface Language a u.s. visitor and a china visitor both use .cn and chiese language ,both got the same result. 3 factors combine many posible google result. any one any clue to clear up it?
.fr focuses on local results while .com on international and it also may vary slightly from datacenter to datacenter
