NAME

       arp - address resolution display and control

SYNOPSIS

       arp hostname

       arp -a [-n]

       arp -d hostname

       arp -f filename

       arp -s hostname ether_address [temp] [pub] [trail]

DESCRIPTION

       The arp program displays and modifies the Internet-to-MAC address translation tables used by the address resolution protocol (see arp(7P)).

       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.

OPTIONS

       -a	Display all of the current ARP entries. The definition for the flags in the table are:

		M	 Mapping; only used for the multicast entry for 224.0.0.0

		P	 Publish; includes IP address for the machine and the addresses that have explicitly been added by the -s option. ARP will
			 respond to ARP requests for this address.

		S	 Static; not learned for the ARP protocol.

		U	 Unresolved; waiting for ARP response.

		You  can  use the -n option with the -a option to disable the automatic numeric IP address-to-name translation. Use arp -an or arp
		-na to display numeric IP addresses.

       -d	Delete an entry for the host called hostname. This option may only be used by the super-user.

       -f	Read the file named filename and set multiple entries in the ARP tables. Entries in the file should be of the form:

		hostname MACaddress [temp] [pub] [trail]

		See the -s option for argument definitions.

       -s	Create an ARP entry for the host called hostname with the MAC address MACaddress.  For example, an Ethernet address  is  given	as
		six  hexadecimal  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. For instance, this system will respond to ARP requests for  hostname  even  though  the
		hostname  is  not its own. The word trail indicates that trailer encapsulations may be sent to this host. arp -s can be used for a
		limited form of proxy ARP when a host on one of the directly attached networks is not physically present on  the  subnet.  Another
		machine can then be configured to respond to ARP requests using arp -s. This is useful in certain SLIP configurations.

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.
