NAME
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_name. The host may be
specified by name or by number, using Internet dot notation.
OPTIONS
-aDisplays all of the current ARP entries.
-dDeletes an entry for the host called hostname.
-sCreates 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 havent 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.
