ARP(8) MachTen System Manager’s Manual ARP(8)

NAME
arp - address resolution display and control

SYNOPSIS
arp hostname
arp -a
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(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 nota-
tion.

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.

-s hostname ether_addr
Create an ARP entry for the host called hostname with the Ether-
net 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. The word trail indicates that
trailer encapsulations may be sent to this host.

-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] [trail]

with argument meanings as given above.
