Here is what you need to do: 1 - download the

geo-lite database
2- load it all into memory
3- make a b tree out of all the ranges available.

4- now you have an ip in your own database that want to know which country it belongs to right? So, lookup that IP in the b tree you create. Whichever range it matched on. Lookup the country for that range.

Now you know which country a given IP belongs to.

You can do whatever you want with that information in your original database

Same thing. Only you need some sort of map. You will lookup each ip in the b tree Then creat a map like {"Iran": 1} If you find another user form iran do Users["iran"] +1

No it doesn't you're doing something that it just happens that I have done before. If you load geoip-lite into memory it takes up to 15sec but it's a one time cost. Then lookups are really fast in b tree. Like I'm talking 9ms response.
