You may provide Google with an IP geolocation data feed to help improve the location accuracy of Google products and services. As a reminder, your use of this service is subject to Google's Terms of Service. Please note that we do not use these locations for DNS frontend assignments. Geographic location does not necessarily correspond with network topology; assignments are optimized based on observed performance for an IP-prefix. Data format In order to allow for frequent updates, you must host a web-accessible CSV file on your server. Google will periodically read from this file. The CSV format is described in Self-published IP Geolocation Data. See an example feed file (.csv) for reference. Note: it may take up to 2 weeks after processing your feed for Google's geolocation index to be updated. Processing status No geolocation feed URL is currently registered.
