The test begins by sending an ICMPv6 ECHO-REQUEST (an IPv6 ping) towards the host under test (HUT). The tester checks for related ICMPv6 responses from either the HUT or other hosts (e.g. routers and/or firewall devices protecting the HUT). If a response is detected from an host other than the HUT then the IPv6 address of this third-party is reported.

The test continues by scanning a set of IPv6 UDP/IP ports. The test sets its' socket tx/rx timeouts to be 2 seconds - consequently the results can take up to 2s per tested UDP port - although this depends heavily upon the filtering your system employs (e.g. firewalls which mark protected ports as 'administratively prohibited' will resolve as PHBTD in much less than the allowed 2 second timeout assuming that your firewall sends an ICMPv6 type 1 code 1 packet in response).

The test finishes by scanning the user-selected IPv6 TCP/IP ports. The IPv6 TCP test sets its' socket tx/rx timeouts to be 1 second - consequently the results can take up to 1s per tested port - although this depends heavily upon the filtering your system employs (e.g. firewalls which mark protected ports as 'administratively prohibited' will resolve as PHBTD in much less than the allowed 1 second timeout assuming that your firewall sends an ICMPv6 type 1 code 1 packet in response).

The tester will indicate the status of the tested ports as either OPEN, STEALTHed or one of a series of other states depending on the positive or negative feedback received from your machine. A typical result is shown in the figure below. Note that if you view the results using an interactive gui-based browser then hovering over specific port numbers produces a pop-up describing the service run on that specific port. For a more detailed explanation of the reported states please read '''[[ScanStatus]]'''.
