MMDB
Porla has basic MMDB support using the JSONRPC method
mmdb.lookup.
Using the MMDB file, the web UI can do IP geolocation for the peer list. It is purely a client-side thing, and Porla itself only provides the APIs.
Setup
To set up MMDB, you need to source an MMDB file such as one from MaxMind or DB-IP.
Then, copy the file to your Porla server, and set the MMDB path in the web UI settings.
