Glossary
ARP (Address Resolution Protocol)
ARP is a TCP/IP protocol for mapping an IP address to a physical machine address that is recognized in
the local network, such as an Ethernet address.
A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The
host on the network that has the IP address in the request then replies with its physical hardware
address.
Inverse ARP (In-ARP), on the other hand, is used by a host to discover its IP address. In this case, the
host broadcasts its physical address and a RARP server replies with the host's IP address.
