### Better IP Filter<\/p>\n
**Better IP Filter** is a lightweight and efficient IP whitelist plugin designed for **Minecraft Paper servers**.
\nIt performs early IP validation during the login process and blocks connections from non-whitelisted IP addresses with minimal performance impact.<\/p>\n
The plugin is intentionally minimalistic and focused on reliability, performance, and ease of use.<\/p>\n
—<\/p>\n
### \u2728 Features<\/p>\n
* IP whitelist filtering on player join
\n* Early connection check using `AsyncPlayerPreLoginEvent`
\n* Extremely lightweight and fast
\n* Toggleable filtering without server restart
\n* IPv4 validation
\n* Persistent storage (`ips.yml`)
\n* No external dependencies
\n* Fully compatible with LuckPerms (Bukkit permissions)<\/p>\n
—<\/p>\n
### \u2699\ufe0f How It Works<\/p>\n
* Player IP is checked **before** the player fully joins the server
\n* Allowed IPs are stored in memory for O(1) lookup
\n* If the IP is not whitelisted, the connection is denied immediately
\n* Designed to add **no noticeable overhead** even on busy servers<\/p>\n
