The answer is choice D-All of these :)
The destination ip address when an ipv4 host sends a DHCPDISCOVER message Because a DHCP client does not have a valid IPv4 address, it must use a broadcast IP address of 255.255. 255.255 as the destination address to communicate with the DHCP server.
<h3>What does the DHCP server do when it receives the Dhcpdiscover message?</h3>
When the lease has expired, the client must start over with the DHCPDISCOVER process. The client ends the lease by sending a DHCPRELEASE message to the DHCP server. The server will then return the client's IP address to the available address pool.
<h3>What is a Dhcpdiscover message?</h3>
The DHCPDISCOVER message contains an identifier unique to the client (typically the MAC address). The message might also contain other requests, such as requested options (for example, subnet mask, domain name server, domain name, or static route). The message is sent out as a broadcast.
