`tracert -d destination` asks Windows to avoid resolving intermediate router addresses into hostnames.

### Why this is right The `-d` option suppresses hostname resolution during the trace. The command still probes the route, but avoids spending time looking up names for the addresses it encounters. ### The concept `tracert` investigates the route toward a destination by probing successive network hops, which are the intermediate routers along the path. The output can help identify where responses stop or become delayed, but it is not a complete explanation of every network fault. Routers may filter or deprioritize probe traffic, so an unanswered hop does not necessarily mean ordinary application traffic cannot pass through it. Hostname resolution is a separate operation from discovering or displaying an address. Using `-d` leaves addresses numeric and can make the trace faster when name lookups are slow or unreliable. ### Terms - **Hostname**: A human-readable name assigned to a computer or network service. - **Router**: A device that forwards packets between networks. - **Hop**: One step through a router on a packet's route. - **Hostname resolution**: Translating a hostname into a network address, commonly through DNS. ### Remember `tracert -d` skips name lookups; it does not skip the route trace.
