Lets say a user behind the computer with the IP address '''192.168.1.3''' wants to check a news site whose address is '''68.1.31.1'''. The computer generates a package containing its IP address, the destination IP address and the request to access website. The computer cannot send the packet through the Internet directly to the website's IP address as it would not receive any response. This is because the host would not know how to reach the computer's IP address of 192.168.1.3 since there might be thousands of devices using that same IP address at any given moment. | Lets say a user behind the computer with the IP address '''192.168.1.3''' wants to check a news site whose address is '''68.1.31.1'''.
