I have just asked a question on How to assign different static IP addresses to the same machine depending on its OS on a network?
I read from this meta answer https://meta.stackexchange.com/a/28230/253264 that suggested
From a desktop support perspective there are certainly cases where a large(r) number of machines will be affected by something, in which case it's appropriate for SF. There are then others that are isolated to a single computer, these tend to be the ones I vote to move to SU.
Since my question is clearly not about a single computer and is external to a single computer, I turned to ServerFault. I thought the question is about how to replicate a network admin strategy on my own (home) network. My question is, however, marked as off-topic, and I did see that homenetwork questions are off-topic. But this is not a single computer issue either.
My question is:
Where should such home/small network questions be asked?
What's the real difference between "professional" networks and the smaller networks that I build for my home or lab with a handful computers?
-- UPDATE --
The question asked here is different from the said duplicate question Which computer science / programming Stack Exchange do I post in? as that question is about the difference among computer science and programming SE sites. It has nothing to do with network administration, whether it's large or small networks. None of the two SE sites in question (Server Fault and Super User) is even mentioned in the question or in the 2 cited answers.
-- UPDATE2 --
This question is not a duplicate of What questions belong on Super User vs Server Fault?, which was cited in the OP and was the cause of this question. That question does not cover the overlapping area of small networks, which could both be for work and for home network.
