Purpose Of The Traceroute Tool
The Traceroute tool shows the network path from the hublist server to a public hub target when intermediate routers answer. It helps explain latency, regional routing, upstream filtering, and where a path stops.
Fields And Controls
Enter a public hostname, IP, or hub URL. The application normalizes the target, blocks unsafe networks, and runs a bounded trace so the request remains safe for the server.
Reading The Results
Each hop is a router or network device along the path. Increasing latency can reveal long routes. Asterisks can mean filtering or rate limiting, not necessarily failure. The final hop may be hidden even when the hub is reachable.
Common Errors
- No Reply After Several Hops: A firewall or provider may block TTL-expired responses.
- High Latency Jump: The path may cross regions or congested transit.
- Trace Fails But TCP Works: The hub can still be healthy because traceroute is often filtered.
