eeThink IP Blocker blocks unwanted IP addresses based on IP blocklists. It monitors network activities in real-time and prevents the connection between a server/website and certain IP addresses or ranges of addresses.

BeeThink IP Blocker effectively bans undesired connections from those computers to a website, mail server, or other Internet server. Being an alternative of PeerGuardian, BeeThink IP Blocker filters 'bad' IP addresses and protects P2P users' computer from unauthorized searches instigated by private agencies and corporations. It keeps safe when using P2P programs such as Limewire, Emule, Vuze, uTorrent or any of the various BitTorrent programs.

This program supports many IP list formats, such as PeerGuardian IPfilter file, Emule IPfilter file, and Apache's .htaccess file. In addition, BeeThink IP Blocker can be used as a simple firewall and the firewall rules are based on IP address, port, protocol, and other factors. If users want to know where their computers communicate, the 'IP address look up' program will tell them more. BeeThink IP Blocker is fully compatible with Windows 2000, XP, 2003, 2008, Vista, Windows 7, in 32-bit and 64-bit. Version 1.2 adds supports for running as a Windows service.
