which utility shows the route a packet takes to reach its destination?
Traceroute is a computer program that sends ICMP packets to show the route a packet takes across an IP network from source to destination. It does this by incrementing the time-to-live (TTL) field by 1 for every successive host until it reaches its destination.
Traceroute is a utility that traces a packet from your computer to an Internet host, but it will show you how many hops the packet requires to reach the host and how long each hop takes.
