The message sent by the DHCP server to let the client know it is able to use the provided IP information is the DHCPACK message. This message is the server's acknowledgment that confirms the client can use the offered IP address and other network configuration parameters.
DHCP Process Overview:
- The client initially sends a DHCPDISCOVER message to locate available DHCP servers.
- The server responds with a DHCPOFFER message offering IP configuration information.
- The client then sends a DHCPREQUEST message to request the offered IP address.
- Finally, the server sends a DHCPACK message to confirm that the client can use the provided IP address and configuration.
This DHCPACK message signals successful lease of the IP address to the client.
