Usage:
arp [-vn] [<HW>] [-i <if>] [-a] [<hostname>] <-Display ARP cache
arp [-v] [-i <if>] -d <host> [pub] <-Delete ARP entry
arp [-vnD] [<HW>] [-i <if>] -f [<filename>] <-Add entry from file
arp [-v] [<HW>] [-i <if>] -s <host> <hwaddr> [temp] <-Add entry
arp [-v] [<HW>] [-i <if>] -Ds <host> <if> [netmask <nm>] pub <-''-
-a display (all) hosts in alternative (BSD) style
-e display (all) hosts in default (Linux) style
-s, --set set a new ARP entry
-d, --delete delete a specified entry
-v, --verbose be verbose
-n, --numeric don't resolve names
-i, --device specify network interface (e.g. eth0)
-D, --use-device read <hwaddr> from given device
-A, -p, --protocol specify protocol family
-f, --file read new entries from file or from /etc/ethers
<HW>=Use '-H <hw>' to specify hardware address type. Default: ether
List of possible hardware types (which support ARP):
