Address Resolution Protocol (ARP) display and control
arp hostname arp -a arp -d hostname arp -f filename arp -p pathname arp -n arp -s hostname ether_addr [pub] [temp]
The -f option causes the specified file to be read and multiple entries to be set in the ARP tables. Entries in the file should be of the form:
hostname ether_addr [pub] [temp]
with argument meanings as given for option -s.
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.
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.
