Does the port scanner scan UDP ports?
No. Port scanning of UDP ports is quite different from TCP ports because UDP is connection-less. In TCP port scan the scanner tries to connect to the given port and based on whether the connection succeeds, fails or times out determine the port state. UDP scanning requires the knowledge of all the protocols which are being examined and sending valid requests to the specified UDP ports. Building support for all possible UDP protocols would require quite a significant amount of time and I'll rather improve other areas of Network Analyzer.
