ARP(8C)                                                                ARP(8C)


NAME
       arp - address resolution display and control

SYNOPSIS
       arp hostname
       arp -a [ vmunix ] [ kmem ]
       arp -d hostname
       arp -s hostname ether_addr [ 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(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
       hostname.

       The  -s  flag is given to create an ARP entry for the host called host���
       name with the Ethernet address ether_addr.   The  Ethernet  address  is
       given  as  six hex bytes separated by colons.  The entry will be perma‐
       nent 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 encapsu‐
       lations 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.
