BeeThink IP Filter filters 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 Filter effectively bans undesired connections from those computers to a website, mail server, or other Internet server. Being an alternative of PeerGuardian, BeeThink IP Filter blocks 'bad' IP addresses and protects P2P users' computer from unauthorized searches instigated by private agencies and corporations.
