Who's going to give me my little brother? A database of IP address and geo-location correspondence

Who can give me a database of IP addresses and geo-location correspondence?
Want to convert the guest's IP address to address location, similar to "Hefei Telecom" and the like. Who can provide a database like this? Or tell me how to convert?

This really has, but there are many ways, Google, Sina, Youdao, etc. have provided IP attribution to query interface, no more than your own server query slow, The second way is QQ has improved a pure version of the Qqwry.datip attribution database, you can search, you can do a own IP attribution query function, but to know that IP is not always constant, the same IP is not always the same place, so this database will be updated, to update, I use this QQW Ry. DAT made an IP attribution to query the interface, you can look at! http://www.521php.com/api/ip.php
