What’s Peerblock?

Peerblock is a powerful IP blocking software that allows you to control and manage incoming and outgoing connections on your computer. It works by blocking specific IP addresses or ranges of IP addresses, effectively preventing certain types of traffic from accessing your network. Peerblock utilizes a regularly updated database of known malicious IP addresses, providing real-time protection against potential threats.


Peerblock operates by analyzing the IP addresses of incoming and outgoing connections and comparing them against lists of known blacklisted IP addresses. These lists contain IP addresses associated with malicious activities, such as spam, malware distribution, or unauthorized access attempts. When an IP address is found on the blacklist, Peerblock blocks the connection, ensuring that your computer remains protected.

In addition to the default blacklist, Peerblock also allows you to create custom lists to block specific IP addresses or ranges that you deem potentially harmful. This capability provides you with greater control over the types of connections allowed on your network.
