IP Data Correction

Ensuring data accuracy is our top priority. We dedicate significant resources to maintaining high data quality and update our dataset daily. However, errors and inaccuracies may still occur.

IP Geolocation Corrections

To report a geolocation correction, please complete the form below. The IP ranges should be formatted according to IP Geofeeds RFC 8805. For more information, you can also refer to this presentation.

Two examples of a correct geofeed submission are provided below. The first is for US addresses, and the second is for DE addresses. Note that the US example does not include a postal code.
