dhcp_dos is the easiest way to do a DHCP Denial Of Service attack.

The DOS attacks supported are:

• Starvation
• Consumption

• -i or --interface: used to specify the interface to use for the attack. You must use this.
• -f or --flood: execute a DHCP starvation attack instead of the default DHCP consumption

• The Scapy Python library
• tcpdump
