IP address redirect based on country

chymoe

I'm looking for a solution to redirect a user based on his/her IP.

I have servers in Asia and servers in the US. A few of my pages are on a US based server which is the primary or root domain name if you will. However when these pages are accessed from China for example, I would like to serve them pages from my China server (my subdomain)... by having the page detect their IP and knowing whether it is based out of China or the US. Is this possible?

Any ideas are appreciated, thanks!

It's possible; however, be aware that some people may fool your scripts. Proxies are one example. But yes you could look at $_SERVER['REMOTE_ADDR'] and see their IP address, and then do a quick "whois" lookup to see where the base of the IP issuer is (Asia or US).

There are a couple of PEAR packages you might want to look at: http://pear.php.net/search.php?q=Net_geo&in=packages

PEAR seems to be a big undertaking... I did find this post: http://www.phpbuilder.com/board/showthread.php?t=10324309

Should suffice? It's not a lookup, but instead I have to predefine the IPs. I would then need to find a listing of all Chinese based Class A or Class B IP addresses and enter them to this script... Would this approach make sense?
