PeerBlock Alternatives
1. BeeThink IP Blocker
BeeThink IP Blocker is a very simple, minimal, and lightweight application that lets you block any and all IP addresses. Along with specific IP addresses, you can also configure the application to block IP ranges. If needed, you can block IP addresses of the entire country too. If you already have an IP address list or programs that actively track problematic IP addresses, you can configure BeeThink IP Blocker to import those lists. Since BeeThink can actively monitor your connections, you can always right-click on any IP addresses or connection and see what data it is sending or receiving. Of course, if the connection is encrypted. i.e. using TLS/SSL, you will see nothing but gibberish. Additionally, you can also lookup IP addresses for its other information like location, ownership, etc. Other features of the application include auto updates to IP address lists, detailed logs, detailed information about ongoing incoming or outgoing connections, ability to exclude IP address, etc. Simply put, you can think of BeeThink as a mini-firewall. If you are looking for a simple yet powerful application that not only lets you block certain IP addresses or IP ranges but also give you detailed additional information regarding various connections, then do try BeeThink IP Blocker.
