ARP(8C)                                                                ARP(8C)

       arp - address resolution display and control

       arp hostname
       arp -a [ vmunix ] [ kmem ]
       arp -d hostname
       arp -s hostname ether_addr [ temp ] [ pub ] [ trail ]
       arp -f filename

       The arp program displays and modifies the Internet-to-Ethernet address
       translation tables used by the address resolution protocol (arp(4p)).

       With no flags, the program displays the current ARP entry for hostname.
       The host may be specified by name or by number, using Internet dot
       notation.  With the -a flag, the program displays all of the current
       ARP entries by reading the table from the file kmem (default /dev/kmem)
       based on the kernel file vmunix (default /vmunix).

       With the -d flag, a super-user may delete an entry for the host called

       The -s flag is given to create an ARP entry for the host called
       hostname with the Ethernet address ether_addr.  The Ethernet address is
       given as six hex bytes separated by colons.  The entry will be
       permanent unless the word temp is given in the command.  If the word
       pub is given, the entry will be "published"; i.e., this system will act
       as an ARP server, responding to requests for hostname even though the
       host address is not its own.  The word trail indicates that trailer
       encapsulations may be sent to this host.

       The -f flag causes the file filename 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 [ temp ] [ pub ] [ trail ]

       with argument meanings as given above.

       inet(3N), arp(4P), ifconfig(8C)

4.3 Berkeley Distribution        May 20, 1986                          ARP(8C)
