Simple Autoban
by DakDak
Simple Autoban is a Forge server mod that bans players who are not on the whitelist, using Minecraft's native ban list for both usernames and IP addresses.
What it does
When an unauthorized player tries to join, the server disconnects them at once and records the username and IP address as permanently banned. The ban uses the game's own ban system, so the entries appear in the usual ban list and stay in place across restarts. Vanilla whitelist must be enabled, since the mod relies on it to decide who is allowed in.
Because both the name and the address are blocked, the mod covers cases where a banned person reconnects under a different account from the same network. Private friend servers, whitelisted communities and servers that need protection against brute-force join attempts can all use it. Players on the whitelist keep normal access and are not affected by the bans.
The mod runs on the server alone, so players join without installing anything. It is published for Forge only, for Minecraft 1.20.1, 1.20.2 and 1.20.4, with 1.0.0 for 1.20.4 as the latest file. The code is open source under the GNU General Public License v3.0 or later.
Key features
Whitelist enforcement
Only players listed on the vanilla whitelist can join, and anyone else is removed from the server as they connect.
Dual username and IP bans
An unauthorized join blocks both the player name and the IP address, which makes returning under another name harder.
Persistent bans
Entries are written to the native ban list, so they remain after the server restarts and can be checked there.
Instant disconnection
The offending connection is closed immediately, before the player gets access to the world.
Compatibility

Use cases
Who it’s for: Server owners who already run the vanilla whitelist and want unauthorized connections to be banned automatically, rather than only refused.
