IP Limit —— Limit the Number of Online Players with the Same IP

✨ Features

IP Connection Limit: Automatically detect and block IP addresses with more than the configured number of connections.
IP Whitelist: Configure trusted IP addresses to bypass checks (e.g., 127.0.0.1 by default).
Threshold Alerts: Send warnings when a specific number of players share the same IP.
Permission Bypass: Players with iplimit.bypass permission are exempt from restrictions.
Rich Text Support: Supports MiniMessage formatting (gradients, click events, hover text, etc.).
Velocity Compatibility: Seamlessly switch configs between Bukkit and Velocity. Use the Velocity version for global IP restrictions across proxies, or the Bukkit version for per-server limits (both versions are non-conflicting).
