thanks Andrew.

I know maxmind from MaxMedia, but not using city yet (and not stable 
yet).I'll look a the PHP interfaces now.

CAIDA site says "*NOTE: NetGeo has not been actively maintained for 
/several years/, and this will probably not change in the foreseeable 
future. As a result, there are several known major issues affecting 
accuracy and service availability. Please be warned that NetGeo may give 
/wildly incorrect/ results, especially for recently allocated or 
re-assigned IP addresses."

It fails to an ARIN Whois lookup also...
