Pathping is a route tracing tool that combines both features of Ping and Tracert commands with some more information that neither of those two commands provides. Pathping is most ideal for a network with routers or multiple routes between the source and destination hosts. The Pathping command sends packets to each router on its way to a destination, and then gets results from each packet returned from the router. Because Pathping computes the loss of packets from each hop, you can easily determine which router is causing a problem in the network.

To display the parameters in Pathping, open a command prompt and type Pathping /?. The parameters for the Pathping command are as follows:

. -4—Specifies that tracert.exe can use only IPv4 for the trace.

. -6—Specifies that tracert.exe can use only IPv6 for the trace.

. -g Host-list—Allows hosts to be separated by intermediate gateways.

. -h maximumHops—Specifies the maximum number of hops before reaching the target. The default is 30 hops.

. -i address—Uses the specified source address.

. -n—Specifies that it is not necessary to resolve the address to the hostname.

. -p period—Specifies the number of seconds to wait between pings. The default is a quarter of a second.

. -q num_queries—Specifies the number of queries to each host along the route. The default is three.

. -w timeout—Specifies the timeout for each reply in milliseconds.
