How to Run Traceroute on Android

Trace a destination, find where replies stop or latency begins to persist, and compare the result with ping and DNS before diagnosing the fault.

Quick steps

1. Resolve or confirm the destination first.
2. Start traceroute and let the hop sequence develop.
3. Identify the first change that continues through later hops.
4. Repeat once to account for routing and rate-limit variation.

What the result means

Traceroute sends probes with increasing hop limits. Routers that return time-exceeded responses reveal their position in the path, while silent hops appear as timeouts.

Traceroute helps show where traffic travels and where replies stop along a network path. It is useful when a destination is slow or unreachable beyond the local router.

Troubleshooting

Repeat the test from the same network and preserve one variable at a time. Check basic reachability first, then move to the protocol-specific test. A single timeout is not enough to identify the failing component.

• Silent hops can still forward traffic normally.
• One slow intermediate reply does not prove forwarding is slow.
• Mobile and load-balanced paths can change between runs.

Common mistakes

• Testing a device on another guest network or VLAN without a route.
• Assuming one scan is a permanent inventory rather than a point-in-time observation.
• Changing several router or device settings before retesting each change.
