It is commonly used to troubleshoot network issues, particularly the ones related to latency and network performance. It is considered an alternative to tracert and it combines ping and tracert commands

you can also use

-q to the number of echoes that is sent out to each router in the path.

-n to prevent resolving intermediate router to their names (DNS)

-p to reduce the wait time for the next ping to be sent out in milliseconds (usually increase this amount if you want to reduce congestions on the network)

Question 24

I want to check latency on ip address 8.8.8.8 with 10 echoes to each router with no resolving dns on intermediate routers and a wait time of 5 milliseconds for each consecutive ping in the network, display this using the command line tool?

Whats the difference of Tracert vs Pathping?

Answer 28

Tracert gets you a list of all the routers between the source and the destination and the time between the individual hops. Pathping brings you all the details that you get with tracert but also includes details like latency and packet loss between all the routers and the source computer.
