       dhcpig - DHCP exhaustion script using scapy network library


       dhcpig [options] <interface> dhcpig -h|--help


       DHCPig initiates an advanced DHCP exhaustion attack. It will consume all IPs on the LAN,
       stop new users from obtaining IPs, release any IPs in use, then for good measure send
       gratuitous ARP and knock all windows hosts offline.

       When executed the script will perform the following actions:

       Grab your Neighbors IPs before they do
          Listen for DHCP Requests from other clients if offer detected, respond with
          request for that offer.

       Request all available IP addresses in Zone
          Loop and Send DHCP Requests all from different hosts  MAC addresses

       Find your Neighbors MAC  IP and release their IP from DHCP server
          ARP for all neighbors on that LAN, then send DHCPReleases to server

       Finally the script will then wait for DHCP exhaustion, (that is no received DHCP OFFERs
       for 10 seconds) and then

       Knock all Windows systems offline
          gratuitous ARP the LAN, and since no additional DHCP addresses are available these
       windows systems should stay offline. Linux systems will not give up IP even when another
       system on LAN is detected with same IP.


       The options of DHCPig are the following. For each option, the default value or default
       behavior is set between parenthesis.
