Gobbler is a tool designed to audit various aspects of DHCP networks, from detecting if DHCP is running on a network to performing a denial of service attack. Gobbler also exploits DHCP and ethernet, to allow distributed spoofed port scanning with the added bonus of being able to sniff the reply from a spoofed host. This tool is based on proof of concept code "DHCP Gobbler" available from networkpenetration.com and the DHCP flaws paper.
