Rogue DHCP Server Attack in an addition to DHCP starvation attacks, when attacker can perform MITM attacks such as sniffing, An attacker who succeeds in exhausting the DHCP Server’s IP address space can found out a Rogue DHCP Server on the network which isn’t under the control of the network administrator. The Rogue DHCP server impersonates a legitimate server and offers IP addresses and other network information to other clients within the network, acting itself …
In a DHCP starvation attack, an attacker floods the DHCP server by sending a large number of DHCP requests and uses all of the available IP addresses that the DHCP server can issue. As a result, the server cannot issue any longer IP addresses, resulting in Denial-of-Service (DoS) attacks, due to this issue, valid users cannot obtain or renew their IP addresses, and thus fail to access their network. An attacker broadcasts DHCP requests with spoofed …
DHCP DHCP Request/Reply Messages a device that already has an IP address can use the simple request/reply exchange Message to get other configuration parameters from a DHCP server. When the DHCP client receives a DHCP offer, the client immediately responds by sending back a DHCP request packet.
