Answer:
route message packets to the final destination.
Step-by-step explanation:
The main function of IP Address is to allocate a unique address to a device on a network so that any information sent to that device can reach it by referring to that particular address.
When one computer sends data, such as an email or a web form, its message gets parsed into small packets that contain the sending computer's Internet address, the receiving computer's address, and part of the message.
IP packet headers contain addresses that identify the sending computer and the receiving computer. Routers use this information to guide each packet across communication networks and connect the sending and receiving computers.
Therefore, one of the function of the IP is to: route message packets to the final destination.
