IP Tunneling: Specifying a Route for IP Packets

What is the process that allows the sender to specify a specific route for an IP packet to take to the destination?

A) IP Forwarding

B) IP Routing

C) IP Tunneling

D) IP Tracing

Final Answer:

IP Tunneling is the process that allows the sender to specify a specific route for an IP packet to take to the destination.

Explanation:

The process that allows the sender to specify a specific route for an IP packet to take to the destination is called IP Tunneling. While IP Forwarding, IP Routing, and IP Tracing play their own vital roles in network communications, they aren't designed to specifically dictate a certain path for an IP packet to take. IP Tunneling, on the other hand, enables encapsulation of an IP packet within another IP packet to allow it to travel across an arbitrary transport network path. In simple terms, IP Tunneling essentially creates a 'tunnel' that the packet follows directly to its destination and this 'tunnel' is a predetermined network route.
