About this Mod

This mod adds per user IP based authorization.

This mod is very useful for offline mode Minecraft servers because it ensures that a user with a username can only join from a specified IP. This avoids impersonating other users and stealing their dear resources.

Frequently Asked Questions

IPAuth server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.17). You can switch loaders with one click in the panel.

Is IPAuth compatible with fabric?

IPAuth officially supports fabric for Minecraft 1.17. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with IPAuth – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if IPAuth consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
