If you previously set up IP Address Geocoding using Ipregistry in an earlier version of Rock, you can now cancel that service. Starting with v17, Rock no longer relies on Ipregistry for IP address geocoding. Thanks to the GeoLite2 Data component created by MaxMind (https://www.maxmind.com), geocoding IP addresses is now handled internally and automatically, so no additional configuration is needed.
You can read about IP Address Geocoding in the Rock Admin Hero Guide.
