DHCP server is used to assign automatic IP address to the client machines which are configured to obtain IP address automatically (default configuration). When a client machine boots it requests an IP address from DHCP server by sending DHCP Discover packet. DHCP server then replies by offering an IP address to the client through DHCP Offer packet. In return client machine requests DHCP server to assign the offered IP address to it using DHCP Request packet and finally the DHCP server assigns the address to the requesting client machine and sends and acknowledgment through DHCP Acknowledge packet. This entire process is known as DORA.
