destination address is the address to which it is assigned) in broadcast mode for address
detection. If no response is received within the specified time, the client will use this
address.
(2) The DHCP client logs on to the network again
When the DHCP client logs in to the network again, it mainly establishes contact with the
DHCP server through the following steps.
● After the DHCP client logs in to the network correctly for the first time and then
logs in to the network again, it only needs to broadcast the DHCP request message
containing the IP address assigned last time, and it is not necessary to send the DHCP
discover message again.
● After receiving the DHCP request message, if the address requested by the client
is not assigned, the dhcp-ack confirmation message will be returned to notify the DHCP
client to continue using the original IP address.
● If the IP address cannot be assigned to the DHCP client (for example, it has been
assigned to other clients), the DHCP server will return a dhcp-nak message. After receiving
the message, the client sends the DHCP discover message again to request a new IP
address.
(3) DHCP client extends lease validity of IP address
The dynamic IP address assigned by the DHCP server to the client usually has a certain
lease term. After the expiration, the server will take back the IP address. If the DHCP client
wants to continue using the address, the IP lease needs to be updated.
In practice, the DHCP client sends a DHCP request message to the DHCP server by
default when the IP address lease term reaches half to complete the IP lease update. If the
IP address is valid, the DHCP server will respond to the dhcp-ack message to inform the
DHCP client that a new lease has been obtained.
