Because UDP is a connectionless transport protocol, you do not need to establish a remote host connection prior to sending and receiving data. You do, however, have the option of establishing a default remote host in one of the following two ways: Create an instance of the UdpClient class using the remote host name and port number as parameters.

UDP Scan (-sU) | Nmap Network Scanning UDP scan works by sending a UDP packet to every targeted port. For most ports, this packet will be empty (no payload), but for a few of the more common ports a protocol-specific payload will be sent. Based on the response, or lack thereof, the port is assigned to one of four states, as shown in Table 5.3. Get UDP - Sender/Reciever - Microsoft Store

UDP uses connectionless communication which has checksums and port numbers.

When a UDP socket is created, its local and remote addresses are unspecified. sendmsg(2)with a valid destination address as an argument.
