Open IP to ASN/Internet Provider Database

If you have an idea on how to improve this project: feel free to start a discussion

Thanks go to the author of hackitu.de for sharing his knowledge about this topic.

If you don't care about the License restrictions - you may want to use the free IPInfo or MaxMind databases. In comparison with these - the database provided by this project has pretty much NO usage restrictions.
