The trace route function allows you to trace the route of IP packets to a user-specified destination system so you can locate the connectivity problem.
The route can involve many different systems along the way. Each system along the route is referred to as a hop. You can trace all hops along the route or specify the starting and ending hops to be traced.
Trace route displays a list of routers between your local network and the destination node. Examine the list of routers that the trace encounters to locate the problem on the network. For example, if the trace stops at a particular router, the problem might lie with that router or somewhere on the network after that point.
Use trace route for both IPv4 and IPv6 connectivity.
