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 pub-
lished ``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 symbolically).
-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.
