TCP/IP Study Notes (3) - IP, ARP, and RARP Protocols

The reason for studying these three protocols together is that they operate at the same layer. The ARP protocol is used to find the Ethernet MAC address of the target host, while IP carries the message to be sent. The data link layer can obtain transmission information from ARP and the data to be transmitted … Read more

TCP/IP Learning Notes (5) - IP Routing

Static IP Routing A Simple Routing Table Routing is one of the most important functions at the IP layer. The previous sections have briefly discussed how routers select routes based on the IP addresses of IP packets. We will not repeat that here. First, let’s take a look at a simple system routing table. Destination … Read more
