To produce more accurate and useful results, PortQry uses a two-step testing process.

Most services don't respond to an unformatted user datagram that's sent to them.If there's no response to a directed datagram, the target port might be FILTERED.This result may not be accurate for one or both of the following reasons:
Typical port scanning tools report that the port has a LISTENING status if the target UDP port doesn't return an Internet Control Message Protocol (ICMP) 'Destination unreachable' message.
