Does anybody know how accurate the ip/location databases are?
Aside from that, is there anywhere I can get access to one for free?
Yes. You can get the free ones from MaxMind.
Countries: http://www.maxmind.com/app/geolitecountry
Cities: http://www.maxmind.com/app/geolitecity
Needs advance knowledge to integrate.
They are pretty much very accurate, but you need to update once per month.
You can download a free copy of IP addresses in relation to countries by clicking here. The data maps IP numbers to the countries where they are. But the data does not give IP addresses in relation to cities. It just gives countries. I am not sure how accurate the data is. But it is fairly up to date.
I hope that helps.
Thanks for the responses guys. I think I came across maxmind during my research but wasn’t sure how good they were. @Steve, I’m pretty good at php and ok using MySQL so integration shouldn’t be too much of an issue for me…I hope.
What I really need is the targeting for cities so I’ll check them out.
Thanks again.
