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).

Hey, this is off topic from the original post but could you tell me what device specifically you have used?

I am going to be moving into a dorm soon and was looking to set up my own VLAN or ehatever you need for a private network because I don’t want to mess with the dorm router. I had a look at a Mikrotik switch (CRS310) but was unsure whether the fan noise would be too loud if I am staying in the same room and more importantly, whether this even allows me to do what I want to do

Edit: I misused the word dorm. It is a shared appartment rented with a couple of other students.
