Protect Your Minecraft Server

Put KittyScan's data to work. Use our tools to harden your Minecraft server against scanners and bots.

KittyScan IP Blocklist

A free, open-source list of IP addresses caught scanning for Minecraft servers detected directly by our honeypots and updated every 24 hours. IPs inactive for 30 days are automatically removed.
Available as a plain list, /16 subnets, or /24 subnets. Used as the default blocklist in KittyBlock and KittyPaper.

KittyPaper Beta

A privacy-focused fork of Paper (Minecraft server software) with hardened default settings and built-in scanner resistance. Ships with the KittyScan IP Blocklist out of the box.
Drop-in replacement for Paper switch without losing any plugins or world data.
