NAME
     arp - address resolution display and control

SYNOPSIS
     arp [ -nv ] hostname
     arp [ -nv ] -a
     arp [ -nv ] -c
     arp -d hostname
     arp -s hostname ether_addr [ temp | permanent ] [ pub ] [ proxy-only ]
     arp -f filename

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

     With no flags, the program displays the current ARP entry for hostname.
     The host can be specified by name or by number, using Internet dot
     notation.

     The arp flags are:

     -a	 Display all of the current ARP entries by reading the table from the
	 routing socket.  Entries that never expire are marked as permanent.
	 Those that can only be changed manually are marked as static.

     -c	 Clear all of the current non-permanent ARP entries from the table.

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

     -s hostname ether_addr
	 Creates an ARP entry for the host called hostname with the Ethernet
	 address ether_addr.  The Ethernet address is given as six hexadecimal
	 bytes separated by colons.  The entry will permanent, i.e., not time
	 out, unless the word temp is given in the command.  An ARP entry can
	 be overwritten by network traffic, unless the word permanent is
	 given.	 If this is specified, only the arp command can be used to
	 change the entry.  Please note that using the permanent keyword
	 causes the entry to be marked as static in arp -a output.  If the
	 word pub is given, the entry is published, that is, this system will
	 act as an ARP server responding to requests for hostname even though
	 the host address is not its own.  If proxy-only is given, the entry
	 is published, but it will not be used by this system for packets send
	 to hostname, which can be useful when hostname is reached by other
	 means such as a PPP link.

     -f filename
	 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:

arp(1M)								       arp(1M)

	   hostname ether_addr [ temp | permanent ] [ pub ] [ proxy-only ]

	 with argument meanings as given above.

     -n	 Causes mapping of IP addresses to hostnames to be suppressed.

     -v	 Causes additional information to be displayed, such as the interface
	 associated with entries and the age of the arp entries. Only a
	 superuser may use this flag.

EXAMPLES
     Command lines are followed by the output.

     A completed successful entry:

	  # arp moose
	  moose (192.26.72.5) at 8:0:69:2:24:3e

     A completed successful entry that is marked permanent and published:

	  # arp rainbow
	  rainbow (192.26.72.3) at 8:0:69:2:4:94 permanent published

     An incomplete entry:

	  # arp ender
	  ender (192.26.72.246) at (incomplete)

     A nonexistent entry:

	  # arp foobar
	  foobar (192.26.72.1) -- no entry
