DHCP spoofing

DHCP spoofing is a type of attack on DHCP server to obtain IP addresses using spoofed DHCP messages. In the cases where the DHCP server is on a remote network, and an IP address is required to access the network, but since the DHCP server supplies the IP address, the requester is at an impasse. To supply access to the network, when the Pipeline receives a DHCP Discover packet (a request for an IP address from a PC on the network), it responds with a DHCP Offer packet containing the configured (spoofed) IP address and a renewal time, which is set to a few seconds. The requester then has access to the DHCP server and gets a real IP address. (Other variations exist in environments where the APP server utility is running.)
