Documentation

Overview

Package arp implements the ARP network protocol. It is used to resolve IPv4 addresses into link-local MAC addresses, and advertises IPv4 addresses of its stack with the local network.

To use it in the networking stack, pass arp.NewProtocol() as one of the network protocols when calling stack.New. Then add an "arp" address to every NIC on the stack that should respond to ARP requests. That is:

if err := s.AddAddress(1, arp.ProtocolNumber, "arp"); err != nil {
	// handle err
}
