DHCPing is a lightweight and featureful security tool written in PERL and designed to test the security of various flavors of DHCP implementations around.
It was originaly written to test DLINK small offices/home offices routers but rapidly became a more general tool ready to test even major implementations like ISC. Many options allow DHCPing users to craft malicious DHCP/BOOTP packets “a la HPING”
Also DHCPing offers several embedded macro commands, several sets of predefined attacks directed toward specific vendors vulnerabilities along with a set of generic attacks.
