The four steps of DHCP (Dynamic Host Configuration Protocol) involve the process by which a client device obtains an IP address and other network configuration parameters from a DHCP server. These steps are: 1. Discover: The client broadcasts a DHCP Discover message on the network to find available DHCP servers. 2. Offer: DHCP servers respond with a DHCP Offer message, offering an IP address and network configuration settings to the client. 3. Request: The client selects one of the DHCP server offers and broadcasts a DHCP Request message, requesting the offered IP address. 4. Acknowledge (Ack): The DHCP server sends a DHCP Acknowledge message to the client, confirming that it can use the requested IP address and providing lease duration and other configuration details.
The four steps of the DHCP leasing process outline how a DHCP client and server negotiate the use of an IP address and related configuration parameters: 1. Allocation: The DHCP server allocates an IP address to the client from its pool of available addresses. 2. Assignment: The DHCP server assigns the allocated IP address to the client for a specific lease duration. 3. Renewal: The client can attempt to renew the lease of the IP address when it reaches half of the lease duration, sending a DHCP Request message to the DHCP server. 4. Reclamation: If the lease expires and the client does not renew, the DHCP server reclaims the IP address back into its available pool for reallocation to another client.
The four messages of DHCP correspond to the communication exchanged between DHCP clients and servers during the IP address allocation process: 1. DHCP Discover: Sent by the client to discover available DHCP servers on the network. 2. DHCP Offer: Sent by DHCP servers in response to a DHCP Discover message, offering an IP address and configuration parameters to the client. 3. DHCP Request: Sent by the client to request the offered IP address from a specific DHCP server. 4. DHCP Acknowledge (Ack): Sent by the DHCP server to confirm that the client can use the requested IP address and provide lease duration and configuration details.
The four steps of DORA (Discover, Offer, Request, Acknowledge) outline the sequence of interactions between a DHCP client and server during the IP address allocation process: 1. Discover: The DHCP client broadcasts a DHCP Discover message to locate available DHCP servers on the network. 2. Offer: DHCP servers respond with DHCP Offer messages, offering IP addresses and configuration details to the client. 3. Request: The client selects one DHCP server offer and sends a DHCP Request message to request the offered IP address. 4. Acknowledge (Ack): The DHCP server sends a DHCP Acknowledge message to the client, confirming that it can use the requested IP address and providing lease duration and configuration parameters.
