The Address Resolution Protocol, or ARP, is a foundation layer of TCP/IP. It translates IP addresses to physical MAC addresses, or locates a gateway through which a machine may be located.
TCP and UDP applications will not need to access ARP directly. The TCPOpen and UDPOpen functions will handle both ARP and DNS operations transparently.
Responses to incoming ARP requests are processed automatically. Resolution of ARP requests follows a simple state machine, as indicated in the following diagram.
