IP logger Fabric

The mod collects the IP address of each player and ties it to that player's username, which lets server staff track possible alternate accounts used to get around a ban. Because a player's address can change, the stored data can go out of date within weeks, and a simple VPN can hide the real address altogether. For that reason the logs are a moderation aid rather than a complete record, and the mod does not claim to catch everyone who tries to avoid a ban.

The mod runs on the server alone, so players join without installing anything. It is written for Fabric and works with the 1.20.1 – 1.20.6 game versions, with files for all six release versions in that range. The 1.1 build for 1.20.6 is the latest file, published on 2025-04-02 after the first release on 2025-03-31. The code is released under the MIT License, and the mod is not open source.

The author notes that players should be told the mod collects this information before they join, so that each player can decide whether to accept it. The data is kept on the server and is not sent to any outside service, but some players may still see the collection of IP addresses as a privacy risk, and server owners should weigh that before enabling it.
