ARP(8N)                 COMMAND REFERENCE                 ARP(8N)



NAME
     arp - address resolution display and control

SYNOPSIS
     arp hostname
     arp -a [ vmunix ] [ kmem ]
     arp -d hostname
     arp -s hostname IEEE802.3_addr [ temp ] [ pub ]
     arp -f filename

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

     With no flags, the program displays the current ARP (Address
     Resolution Protocol) entry for hostname; hostname can be
     specified as either the name (hostname(1N)) selected for the
     workstation or as the internet address (inet(4N)).

OPTIONS
     -a  The program displays all current ARP entries by reading
         the table from the file kmem (default /dev/kmem) based
         on the kernel file vmunix (default /vmunix).

     -d  A superuser may delete an entry for the host called
         hostname.

     -s  Create an ARP entry for the host called hostname with
         the IEEE 802.3 address IEEE802.3_addr; an example of
         that address is listed here.

              arp -s hosty 8:0:11:0:6:11 [ temp ][ pub ]

         In this example, hostname is hosty and the
         IEEE802.3_addr is 8:0:11:0:6:11.  The IEEE 802.3 address
         components are hexadecimal and must be separated by
         colons.  If temp is specified, the entry is temporary
         and is flushed after 20 minutes.  If pub is specified
         the entry is "published", e.g., this system responds to
         ARP requests for hostname even though the host name is
         not its own.

     -f  Reads the filename and sets multiple entries in the ARP
         tables; entries in the file should be of the form

              hostname IEEE802.3_addr [ temp ] [ pub ]

         with argument meanings as given above.
