UdpScan

Lists the UDP services for the scanned host.

Internet Scanner sends a collection of UDP packets to each UDP port to check if it is active, and then listens for a response. The type of response (or the lack of a particular type of response) indicates if the port is active. As the UDP port scanner uses the UDP and ICMP protocols, which are classified as unreliable protocols, results can vary between scans. Furthermore, many operating systems limit the rate at which they send ICMP error messages, which can further limit the effectiveness of this scan.
