IP Whitelist (Fabric)

🛡️ IP Whitelist

A lightweight, server-side Fabric mod that lets admins control who joins based on their IP addresses.

By default, the mod is disabled when first installed to prevent you from locking yourself out. Join your server, then run /ipwhitelist add <yourname> followed by /ipwhitelist on to secure your server.

Features

• IP-Based Security: Blocks connections before the player even joins the world.
• Private servers friendly: Doesn’t rely on UUIDs or other authentication methods that won’t work on offline-mode servers.
• Simple & Lightweight: Basic protection that works without having to set up complex authentication systems.

Commands

All commands require OP.

Configuration

The mod creates a folder at /config/ipwhitelist/ with two files:

1. ip-whitelist.txt: A simple list of allowed IPs (one per line). You can edit this manually and run /ipwhitelist reload.
2. ip-whitelist-config.properties: Stores the enabled=true/false state.
