Address Resolution Protocol (ARP) display and control
arp [-n] hostname arp [-nv] -a arp [-v] -d -a arp [-v] -d hostname [pro [iface_name]] arp -s hostname ether_addr [temp] [pub [pro [iface_name]]] arp -f filename
hostname ether_addr [pub] [temp]
with argument meanings as given for the -s option.
If pub is given, the entry is “published.” That is, this system acts as an ARP server, responding to requests for hostname, even though the IP address that's mapped to hostname isn't the address of this system.
The entry is permanent unless the word temp is given in the command.
Specify the pro string to create or delete a proxy-only ARP entry.
The iface_name argument is the name of the interface (e.g. fxp0).
The arp utility displays and modifies the Internet-to-Ethernet address translation tables used by the Address Resolution Protocol (ARP).
With no options, the utility displays the current ARP entry for hostname. The host may be specified by name or by number, using Internet dot notation.
