DESCRIPTION
DHCP starvation is attacking a DHCP server by sending a lot of requests to it. This lead
to server's address pool exhausting after which DHCP server is not able to respond clients
and give them new leases.
dhcpstarv is tool that implements DHCP starvation attack. It requests DHCP leases on
specified interface, save them and renew on regular basis.
When a rogue DHCP server appear in network with DHCP infrastructure some clients can get
wrong network settings. Those rogue servers can be switched by users by accident. The only
solution to issue is to disconnect such server from network. But it takes a lot of time
to discover rogue server if network is complicated, i.e. there are many network devices in
it. As a temporary solution you can attack rogue DHCP server until find and disconnect it
from network.
