All I need is a way to query an NTP Server using C# to get the Date Time of the NTP Server returned as either a string or as a DateTime. 123); //NTP uses UDP
What is User Datagram Protocol (UDP/IP)? UDP is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communications by not requiring what’s known as a “handshake”, allowing data to be transferred before the receiving party agrees to the communication.

As you can see from the picture above, there are three open UDP ports on the target host – 123, 137, and 51690. UDP is used for some routing update protocols like RIP(Routing Information Protocol). Normally used for real time applications which can not tolerate uneven delays between sections of a received message. Following implementations uses UDP as a transport layer protocol: NTP (Network Time Protocol) DNS (Domain Name Service) BOOTP, DHCP. Mar 30, 2016 · UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768). Application examples that often use UDP: voice over IP (VoIP), streaming media and real-time multiplayer games.

What is UDP (User Datagram Protocol)? UDP (User Datagram Protocol) is a communications protocol that is primarily used for establishing low-latency and loss-tolerating connections between applications on the internet. It speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party. Arduino - UdpNtpClient
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.
