Test, check and troubleshoot your connection

A web browser can't send the low-level network packets traceroute needs, so we don't show made-up hop results here. Use a trusted external tool, or run tracert example.com (Windows) or traceroute example.com (Mac/Linux) on your computer.

Browsers can't reliably test whether an arbitrary TCP port is open on your connection. An external service can check ports on your public IP from the outside.
