Ping

Ping a host, or run a traceroute to see which way traffic gets there.

You are using the tools as a guest: up to 20 runs per hour, and the port scanner only scans your own IP address. A free account gives you full access.

Ping

Traceroute

Shows which routers traffic passes through on its way to the host.

Traceroute (to internet / jegon)

A traceroute from your own machine shows the path from your network to the target. A web page cannot start one on your computer, so run the command yourself in a terminal and paste the result below if you want to save it.

Target (domain or IP)

The target may only contain letters, digits, dots, colons and hyphens.

Windows

Open Command Prompt or PowerShell. Windows looks up the hops' PTR names by itself (name [ip]).

Linux

Run in a terminal. Names (PTR) are shown by default. If the program is missing: sudo apt install traceroute (Debian/Ubuntu) or sudo dnf install traceroute (Fedora/RHEL).

Copied

If it ends in only * * * (the target does not answer UDP, which the standard traceroute uses), use ICMP instead. This needs sudo:

Or with mtr, which shows both name and IP per hop:

Hops that only show an IP address have no PTR record. Hops with * do not answer traceroute, but traffic can still pass through them.

If you have a jegon account you can save your traceroute here. It is linked to your login together with your IP and browser, so you can find it again.
