ARP Table

This chapter introduces ARP Table.

35.1  ARP Table Overview 

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP 
address) to a physical machine address, also known as a Media Access Control or MAC 
address, on the local area network. 
An IP (version 4) address is 32 bits long. In an Ethernet LAN, MAC addresses are 48 bits 
long. The ARP Table maintains an association between each MAC address and its 
corresponding IP address. 

35.1.1  How ARP Works

When an incoming packet destined for a host device on a local area network arrives at the 
Switch, the Switch's ARP program looks in the ARP Table and, if it finds the address, sends it 
to the device.
If no entry is found for the IP address, ARP broadcasts the request to all the devices on the 
LAN. The Switch fills in its own MAC and IP address in the sender address fields, and puts 
the known IP address of the target in the target IP address field. In addition, the Switch puts all 
ones in the target MAC field (FF.FF.FF.FF.FF.FF is the Ethernet broadcast address). The 
replying device (which is either the IP address of the device being sought or the router that 
knows the way) replaces the broadcast address with the target's MAC address, swaps the 
sender and target pairs, and unicasts the answer directly back to the requesting machine. ARP 
updates the ARP Table for future reference and then sends the packet to the MAC address that 
replied.
