Path Of The Packets

Path Of The Packets

You can use traceroute to determine the network path packets follow from your machine to some host server. For instance, if I want to know path between my laptop (connected to airport wifi) and my website joshbranchaud.com, I can run the following command:

$ traceroute joshbranchaud.com
traceroute to joshbranchaud.com (198.74.60.157), 64 hops max, 52 byte packets
