Hi all,

Can any of you please recommend some IP-to-geo mapping database / web service ?

I would like to get resolution down to city if possible.

The gold standard is MaxMind GeoIP. http://www.maxmind.com/ There are a couple "free" ones I've seen, but they are quite a bit less accurate. I can't think of them off the top of my head. As a major caveat, all geolocation services do have some degree of inaccuracy, because the sources of data are very diverse. (Some ISPs provide complete subnet maps to MaxMind and other providers, whereas some data is scraped from WHOIS or provided by inference from end-users.) -- -- Todd Vierling <tv@duh.org> <tv@pobox.com> <todd@vierling.name>
