NAME
     arp - address resolution display and control

SYNOPSIS
     arp hostname

     arp -a [ unix [ kmem ] ]

     arp -d hostname

     arp -s hostname ether_address [ temp ] [ pub ] [ trail ]

     arp -f filename

DESCRIPTION
     The arp  program  displays  and  modifies  the  Internet-to-
     Ethernet  address  translation  tables  used  by the address
     resolution protocol [arp(7)].

     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.

     The following options are available:

     -a   Display all of the current ARP entries by  reading  the
          table  from  the file kmem (default /dev/kmem) based on
          the kernel file unix (default /stand/unix).

     -d   Delete an entry for the  host  called  hostname.   This
          option may only be used by the super-user.

     -s   Create an ARP entry for the host called  hostname  with
          the   Ethernet  address  ether_address.   The  Ethernet
          address is given as six hexadecimal 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, for instance, this
          system will respond to ARP requests for  hostname  even
          though  the  hostname  is  not its own.  The word trail
          indicates that trailer encapsulations may  be  sent  to
          this host.

     -f   Read the file named filename and set  multiple  entries
          in  the  ARP  tables.  Entries in the file should be of
          the form

               hostname ether_address [ temp ] [ pub ] [ trail ]

          with argument meanings as given above.
