Direct IPv4 Navigation Blocker is a free Chrome add-on developed by FikesMedia. This tool prevents Chrome from accessing websites through direct IPv4 addresses. It effectively blocks Chrome from reaching sites through IP addresses, which can be beneficial for environments like K12 schools looking to restrict access to proxy sites that are not categorized by regular filtering systems.

This add-on provides a simple yet effective solution for network administrators or individuals wanting to enhance their web filtering capabilities within the Chrome browser. By restricting access through direct IPv4 addresses, it offers an additional layer of control over website access, particularly in educational or controlled environments.
