Free IP / Geolocation Database And API: WIPmania

WIPmania provides IP to country database and API which is free to use for both personal & commercial projects.

The database comes in SQL, CIDR & text formats & updated in every 2 months.

If you don’t want to use the database and use the API, a simple query like:

http://api.wipmania.com/123.45.67.89?google.com

returns you a 2 digit country code (google.com is the URL where the query is made from). API usage is free until 10,000 queries/day.
