appended with the frame head and frame end of the data link, and the packet is put into frame. Finally, the physical layer is converted to bits-per-unit data. Therefore, the IP address is the network layer used to identify the logical address of different locations, its length is 32 bits, and at the data link layer is the MAC (media access control)

different hosts depending on the network on which it resides. This is accomplished by configuring the router to notify multiple sites in the Internet that there is the same unicast route. Therefore, an anycast address does not refer to a host in the Internet, but rather to a host that is "most suitable" or "closest" to the anycast address. Anycast addresses are most commonly found in a computer that provid
