dhcpig Usage Example

Exhaust all of the available DHCP addresses using the eth0 interface (eth0):

root@kali:~# pig.py eth0
WARNING: No route found for IPv6 destination :: (no default route?)

Sending DHCPDISCOVER on eth0
waiting for first DHCP Server response on eth0

Packages and Binaries:

dhcpig

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.

It is based on the scapy library and requests admin privileges to execute. It has been tested on multiple Linux distributions and multiple DHCP servers (ISC, Windows 2k3/2k8, …).
