arp - address resolution display and control
SYNOPSIS
arp
hostname
arp -a
arp -d
hostname
arp -s
hostname
ether
_
address
[ temp ] [ pub ]
DESCRIPTION
The arp command displays and modifies the tables that the address resolution proto-
col uses to translate between Internet and Ethernet addresses.
With no flags, arp displays the current ARP entry for
host_
n
ame
. The host may be
specified by name or by number, using Internet dot notation.
OPTIONS
-a Displays all of the current ARP entries.
-d Deletes an entry for the host called
hostname
.
-s Creates an ARP entry for the host called
hostname
with the Ethernet
address
ether
_
address
. The Ethernet address is given as six hex bytes sepa-
rated by colons. The entry will be permanent if the words following -s
includes the keyword temp. Temporary entries that consist of a complete
Internet address and a matching Ethernet address are flushed from the arp
table if they havent been referenced in the past 20 minutes. A permanent
entry is not flushed.
If the words following -s include the keyword pub, the entry will be pub-
lished; i.e., this system will act as an ARP server, responding to requests
for
hostname
even though the host address is not its own.
