Improved IP localization

We are constantly improving the service. Up to now the ratio of locatable IPs was not satisfying. Only about 70% of the accesses were resolved to a location. This was mainly because the project does not yet have full coverage. The project is a great idea and will certainly evolve over time. At the moment quality and coverage is just not where we would like it to be, so was looking for a solution.

We found an acceptable solution in still using the database as the primary lookup source. In case an IP can not be found in the database performs a second lookup against the website. That way the coverage and quality of the two services are aggregated. With this solution reaches a ratio of locatable IP way above 90%!
