Cleaning up the Sitecore log for Geo IP Location

Since Sitecore 8.1 the Geo IP lookup service is pre-configured. If you don't purchase the service and look into your logs you see the following error

The remote name could not be resolved: ''

To fix it, simply add a patch config file to disable the service. Have a look at the Sitecore documentation1 if you need further information about the geolocation service.
