arp [-v] [-i <if>] -d <hostname> [pub][nopub] <-Delete ARP entry
arp [-vnD] [<HW>] [-i <if>] -f [<filename>] <-Add entry from file
arp [-v] [<HW>] [-i <if>] -s <hostname> <hwaddr> [temp][nopub] <-Add entry
arp [-v] [<HW>] [-i <if>] -s <hostname> <hwaddr> [netmask <nm>] pub <-''-
arp [-v] [<HW>] [-i <if>] -Ds <hostname> <if> [netmask <nm>] pub <-''-
