It is mostly used when there is a conflict, which can be detected by either DHCP servers or clients to determine whether an IP address is already in use on the network before leasing or using the address. The packet might also contain other requests, such as requested options (for example, subnet mask, domain name server, domain name, or static route).ĪLSO READ: Linux disable IPv6 properly (with or without reboot)ĭHCP client sends it to server indicating configuration parameters (e.g., network address) invalid. Step-1: The client sends a broadcast DHCPDISCOVER packet to the network, which contains an identifier unique to the client (typically the MAC address). Following screenshot shows the steps how to assign an IP address to the client. A DHCP server uses DHCP options to provides information to its clients. Assigning IP addresses dynamically through DHCP is just only one function of the protocol. Before a deep investigation, I would like to refresh your memory regarding how Dynamic Host Configuration Protocol ( DHCP) works.ĭHCP is a network management protocol that is enable us to dynamically configure a client. There are some tools out there that can help, but the simplest method for me is to use Wireshark to detect the rogue DHCP server. Recently, I came across a question on “” about how to detect a rogue Install and Configure DHCP server in your network.
