Which UVNC should I use?

[ianvass]

Hey folks, rank newbie here.

So I see info on setting up UVNC in the FAQs, but absolutely no info on which type of UVNC I should use in the first place. I am quite confused.

Here is what I need:

I am looking to remotely administer from Win 10 laptop a different Win 10 laptop that could switch locations at any time. The VNC I used 15 years ago required the user to give the administrator the IP address, but since this could change at any time depending on the laptop's location, and I need to be able to control the machine before login no matter the location or IP address, I'm not sure what to do at this point. What version should I use? How do I set it up so that I am able to log in regardless of what IP address the machine is so that no one on the receiving end needs to do a dang thing?

Thanks!
