About P2B files

The .p2b file is a binary IP blocklist used by PeerBlock and PeerGuardian. It stores ranges of IP addresses to block peer-to-peer tracking and malicious servers. The main disadvantage of this format is its proprietary binary structure. You cannot open it with standard text editors. Furthermore, PeerBlock is obsolete legacy software. Modern firewalls and DNS sinkholes like Pi-hole or pfSense require plain text lists. You must convert .p2b to TXT, CSV, or P2P to reuse the blocked IP data. Because this is a closed, compiled format, standard online converters usually fail to process it. Just drag and drop your file into convert.guru to identify the format, view it, and convert it when possible. We can inspect the internal data to extract readable IP addresses.

Convert.Guru analyzes your P2B file, detects the exact format, and lets you read the text inside.
