ARP.exe

ARP.exe is used to display or modify the IP-to-Physical address translation tables.

System Command ARP.exe

Displays and modifies the IP-to-Physical address translation tables used by address resolution protocol (ARP).

Syntax

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr] [-v]

Parameter

-a Displays current ARP entries by interrogating the current protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If more than one network interface uses ARP, entries for each ARP table are displayed. -g Same as -a. -v Displays current ARP entries in verbose mode. All invalid entries and entries on the loop-back interface will be shown. inet_addr Specifies an internet address. -N if_addr Displays the ARP entries for the network interface specified by if_addr. -d Deletes the host specified by inet_addr. inet_addr may be wildcarded with * to delete all hosts. -s Adds the host and associates the Internet address inet_addr with the Physical address eth_addr. The Physical address is given as 6 hexadecimal bytes separated by hyphens. The entry is permanent. eth_addr Specifies a physical address. if_addr If present, this specifies the Internet address of the interface whose address translation table should be modified. If not present, the first applicable interface will be used.

Examples

Adds a static entry. arp -s 157.55.85.212 00-aa-00-62-c6-09 Displays the arp table. arp -a
