I may have misused the word dorm. It is a shared appartment rented with a couple other students.
My goal is basically to set up a private network inside the network used by the other people I share the apartment with so I can tinker with stuff like setting my own DNS server up for the network without possibly impacting the other people in case of failure. My naive impression was that I would need to use a VLAN to accomplish that.
In regards to your idea of using multiple devices I kind of agree but I want to keep the initial cost and energy usage low for now which is why I am trying to find a device I can use for this but also reuse in the future for something else if I want to upgrade (or just retire it without too much sunk cost).
Definitely this. There are so many minor things regarding formatting or how something you wrote may sound off to someone else that you generally won’t know or notice wirhout an outside perspective
