Second I don't understand how this works exactly, I intend to create a

spoofing attacks, should I create the entry on arp add/old and remove on

Replying to myself because I made a typo in this paragraph. I meant to say:
"should I create the ARP entry on the add/old action and remove on del"

This dhcp-script seems to work just fine, not sure what the point of
arp-add/arp-del is though:
#!/bin/sh
action=$1 hw_addr=$2 hostname=$3
case $action in
add|old) arp -s $hostname $hw_addr ;;
del) arp -d $hostname ;;
