About the Traceroute
Traceroute maps the network path from this server to a target host, revealing each router hop along the way and how long each one takes to respond. The results stream live, hop by hop, so you can watch the route build out in real time. It is the go-to tool for pinpointing where latency spikes or routing failures occur between two points on the internet.
How to use
- Enter the destination hostname or IP address.
- Click Start to begin tracing the route.
- Watch each hop and its latency appear as it is discovered.
- Identify any hop where latency jumps or replies stop.
Frequently asked questions
- What is a hop?
- A hop is one router the packet passes through on its way to the destination. Traceroute lists them in order with the latency to each.
- Why do some hops show asterisks?
- An asterisk means that router did not reply within the timeout. Many routers deprioritize or block traceroute probes, which is usually harmless.
- Where is the problem if latency spikes mid-route?
- A spike that persists for all later hops points to congestion or a slow link at that hop. A single high hop that recovers afterward is often just a busy router.
