IpLogger
by NasheedPog
IpLogger keeps a record of username and IP address pairs for a Fabric server, so administrators can look up a player's address without searching the console logs.
What it does
The mod stores each username with the IP address it connected from, and it can check whether a connection appears to come through a VPN tunnel back to a home address. By default an address only shows up in the server console logs, where it has to be found by reading through them, so this record makes that lookup a single step. It runs on the server alone, so players join without installing anything. Files are released under the MIT License, which is not open source, for 1.21.1 – 1.21.4.
Key features
Username and IP records
Each player's username is stored with the IP address seen at login, replacing a manual search of the console output.
VPN tunnel check
The mod reports when a connection seems to route through a VPN, showing the address that was recorded for that player.
Server-only setup
Only the server runs the mod, so clients need nothing installed and the lookup stays with the administrator.

What the author says
Remember that a simple VPN would result in storing the incorrect IP of a player. This mod makes no attempt to check if a player uses a VPN or to tunnel back to their home-IP - it only stores the IP available in the console logs. All IPs are by default available in the server console logs, but reading through them to…
