How Yesinia Works???
Whenever user power up the machine it start searching the IP address. DHCP server offer the machine for IP address,as and when our machine respond to the request of DHCP server. DHCP server provide the IP address from its pool and allocate it your machine mac address.
So yersinia send many discover packet to DHCP server using different MAC Address so all the free IP in DHCP server used ,so genuine request from machine would be unsatisfied.
