What is the first message in the DHCP DORA handshake?

Explanation:
The first message is DHCPDISCOVER. When a client has no IP address yet, it doesn’t know which DHCP server to contact, so it broadcasts DHCPDISCOVER on the local network to find any available DHCP server. This starts the DORA sequence—Discover, Offer, Request, Acknowledge. A server that hears the discover replies with a DHCPOFFER, offering an IP and other network settings. The client then selects an offer and sends a DHCPREQUEST to request that IP, and the chosen server confirms with a DHCPACK. Technically, the discover message is sent via UDP from port 68 to port 67, with the client IP set to 0.0.0.0 and the destination broadcast address to reach any server on the subnet.
