PeerBlock is an advanced IP blocking utility that provides users with granular control over how their PC interacts with other devices on the Internet. In simpler terms, it allows users to block connections to servers and sites that are known to be troublesome or dangerous, offering a customizable approach to online safety. Users can select what to block from pre-made lists or create and import their own. PeerBlock is open-source freeware actively maintained by the PeerBlock project.

When you first run PeerBlock, a setup wizard helps configure its options. By default, PeerBlock blocks anti-P2P organizations, ads, spyware, and educational institutions. An important option, Always Allow HTTP, enables connections over ports 80 and 443, typically used for web browsing, even if those addresses are in your blocklist. This ensures that legitimate browsing activities are not disrupted while retaining protection against other threats. The setup process is guided by clear, step-by-step recommendations that explain each option, minimizing confusion for users. For further clarification, PeerBlock provides an online User Guide and extensive documentation.

Once installed, PeerBlock efficiently updates its threat lists and displays the data within its straightforward interface. The interface includes two primary tabs, Protection and Settings, with the latter extending across two pages. The system tray icon provides quick access to the tool's main console and essential features, such as enabling or disabling the application, HTTP options, and support functions. The software's auto-update feature ensures that changes to blocklists are synchronized immediately, maintaining maximum effectiveness against emerging threats.

New developments in PeerBlock

In recent updates, PeerBlock has introduced enhancements such as better compatibility with modern operating systems and improved memory efficiency. Additionally, the application now supports IPv6, ensuring that users are protected as internet protocols evolve. A scheduling feature allows users to automate updates, ensuring their blocklists stay current without manual intervention. These updates address some criticisms of earlier versions, particularly regarding compatibility and usability.

Comparison: PeerBlock vs. GlassWire

While PeerBlock is a robust IP blocking tool, it is not without competition. GlassWire, a modern network monitoring and firewall software, offers overlapping yet distinct features. GlassWire emphasizes real-time network traffic visualization, giving users a detailed view of what applications and servers their device connects to. Unlike PeerBlock, which relies on blocklists, GlassWire provides customizable alerts for unusual network behavior. Furthermore, GlassWire’s interface is more user-friendly and visually engaging, appealing to less technically inclined users.

However, PeerBlock has the advantage of being completely free and open source, whereas GlassWire offers a freemium model with advanced features locked behind a paywall. PeerBlock’s focus on direct IP blocking makes it particularly appealing to users prioritizing privacy over network analytics. GlassWire, on the other hand, is better suited for those who want detailed insights into their network activity.

Bottom Line

In summary, PeerBlock remains an excellent choice for users seeking a lightweight, no-frills IP blocker with robust customization options, while GlassWire is ideal for those needing a more comprehensive network management solution. Both tools cater to different needs, with PeerBlock excelling in simplicity and specificity, and GlassWire standing out for its versatility and visual appeal.

Developer’s Description

Block all communications with selected IP and IP ranges with ease.
PeerBlock lets you control who your computer "talks to" on the Internet. By selecting appropriate lists of "known bad" computers, you can block communication with advertising or spyware oriented servers, computers monitoring your p2p activities, computers which have been "hacked", even entire countries. They can't get in to your computer, and your computer won't try to send them anything either.
