NetBSD 6.1.5 - man page for arp (netbsd section 8)

ARP(8)				   BSD System Manager's Manual				   ARP(8)

NAME
     arp -- address resolution display and control

SYNOPSIS
     arp [-n] hostname
     arp [-nv] -a
     arp [-v] -d -a
     arp [-v] -d hostname [proxy]
     arp -s hostname ether_addr [temp] [pub [proxy]]
     arp -f filename

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

     Available options:

     -a      The program displays all of the current ARP entries.

     -d      A super-user may delete an entry for the host called hostname with the -d flag.  If
	     the proxy keyword is specified, only the published ``proxy only'' ARP entry for this
	     host will be deleted.  If used with -a instead of a hostname, it will delete all arp
	     entries.

     -f      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]

	     with argument meanings as described below.

     -n      Show network addresses as numbers (normally arp attempts to display addresses sym-
	     bolically).

     -s hostname ether_addr
	     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.  If the word proxy is also given, the published entry will be a ``proxy
	     only'' entry.

     -v      Display verbose information when adding or deleting ARP entries.
