DNS Leak Test

Open-source script that tests a VPN connection for DNS leaks

Pluginfreeglobal

DNS Leak Test is a free, open-source script (and companion web test) that checks whether a VPN connection is leaking DNS queries outside its encrypted tunnel, which would expose browsing activity to an ISP despite using a VPN. It's for VPN users and privacy-conscious individuals who want to verify their setup is actually protecting their DNS traffic. Available as a Bash or Python script for Linux and macOS.
