IP Whitelist (Fabric)
by ticua07
IP Whitelist lets server admins limit who can join by IP address, checked before a player enters the world.
What it does
Admins list allowed IP addresses in a plain text file, one per line, and reload the list with a command after editing it by hand. Connections from addresses outside the list are blocked before the player finishes joining, so the restriction does not depend on player names or UUIDs.
Because it does not rely on UUIDs, the whitelist also works on servers running in offline mode, where other authentication methods fail. Players join by adding their address with a command run from the server, and a stored enabled flag turns the check on or off. The mod is disabled after its first install, which keeps an admin from locking themselves out before the list is set up.
The mod is server-side only and runs on Fabric, targeting 1.21.10 and 1.21.11 with the 1.0.2 build for 1.21.11 as the latest file. It is released under the GNU General Public License v3.0 only and is open source.
Key features

Joins are checked against a list of allowed IP addresses, so only listed addresses can enter the server.
Early connection blocking
Connections from unlisted addresses are refused before the player reaches the world.
Plain text allow list
Allowed addresses are kept in a simple file with one address per line, edited by hand.
