The main function of the router can be understood as realizing the forwarding of information. Therefore, we call this process the addressing process. Because the router is between different networks, it is not necessarily the final receiving address of the information. So in the router, there is usually a routing table. According to the final address of the information transmitted by the transmitting website, find the next forwarding address, which network should be. In fact, to put it simply, it is like a courier company to send mail. The mail does not arrive at the final destination instantly, but through the sorting of different sub-stations, constantly approaching the final address, so as to realize the delivery process of the mail. The router addressing process is similar. The final address is matched in the routing table, and the next forwarding address is determined by an algorithm. This address may be an intermediate address, or it may be the final arrival address. [4]
