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. IP Blocker can be successfully used on Windows website server machines, in a production environment, to easily ban country IP addresses with Apache's .htaccess files. IP Blocker can be used as a lightweight firewall and the IP blocking rules are based on IP address, port, protocol, and other factors. IP Blocker is fully compatible with Windows 2000, XP, 2003, 2008, Vista, Windows 7, Windows 8, Windows 10 and Windows 2012, in 32-bit and 64-bit.
