DESCRIPTION

'QQWry.Dat' http://www.cz88.net/fox/ is a file database for IP lookup. It provides some useful infomation such as the geographical position of the IP, who owns the ip, and so on. This Module provides a simple interface for this database.

Caveat: The 'QQWry.Dat' database uses gbk encoding, this module doesn't provide any encoding conversion utility, so if you want some other encoding, you have to do it yourself. (Encode is a great module which can help you much.) In addition, the information retrieved from this database is mostly in Chinese, so it won't suited for world wide usage, ;-)
