Traceroute Online

When a website is slow or unreachable from one place but fine from another, the problem is usually somewhere along the network path. Traceroute shows that path: every router (hop) between a test location and the target, with how long each one takes to answer. This tool runs the traceroute from real probes in the country or region you choose, so you can see the route from your customers' side of the world, not just your own. Switch to MTR to send several packets per hop and see packet loss as well as average, best and worst times.

How to use Traceroute Online

1. Enter a domain name or IP address.
2. Choose where to test from (a region or a country) and how many locations.
3. Pick Traceroute or MTR, and ICMP, TCP (with a port) or UDP.
4. Click Run traceroute. Results appear in a few seconds, hop by hop.

When it comes in handy

• Finding where a slow or dropped connection breaks down.
• Checking the route from a customer's country to your server or CDN.
• Giving your hosting provider or ISP evidence of a network problem.

Frequently asked questions

What do the asterisks (*) mean?

That hop did not answer in time. Many routers ignore traceroute packets on purpose, so a few "*" hops in the middle are normal as long as later hops answer.

Traceroute or MTR?

Traceroute shows the path once. MTR sends several packets to every hop and shows packet loss and jitter, which is better for finding an unstable link.

Why use TCP?

Some firewalls block ICMP and UDP. A TCP traceroute to port 443 follows the same path as real HTTPS traffic, so it often gets further.

Where do the tests run from?

From the free Globalping network: thousands of probes on home, business and data-centre connections worldwide. The test starts from your browser; up to 250 tests an hour are free.
