Hello,

I branched off on a tangent with my answer and it only finds reachable IP’s.  
I don’t have an answer for ports at this time and would have to seek one.

Back to work and busy these days…

Keep looking!

And I am back already!

I did find this:

And so far got this and it did detect an active server port:

I got a “false” if I looked for a port “12347” that was not active.

Using the server example:

I may explore this more later…  
It is my first time exploring this also.
