what's a private lan, and what's it for? What's the topology of the building
divided into?
Nothing is currently on the private LAN. For things where we might not want it 100% open without any password we can use the private LAN. This is useful if we want to have e.g. video streaming equipment that is isolated and prioritized over the general network so it won't stop working when hundreds of visitors are using the open wifi.
does that mean that if something plugs into an ethernet port, it's going to be
on a different subnet from the stuff connected to the wifi? Do we need to do
that?
No.
My preference would be to keep things simple. If things are more complicated
then it creates a larger divide between the knows and the know-nots, and that
leads to concentration of understanding of the infrastructure. If there has to
be complexity of our system, for example two different subnets for different
purposes, I would request that it be documented on the wiki in plain language
so that it's not a mystery.
Yes agreed. People who don't work on Omni infrastructure should probably never encounter the private subnet. At most they might see a different wifi SSID with a password that they don't have.
I have learned a bit of network stuff over the years but there's still so much
I don't understand, and I can only imagine how opaque it all is for people with
less knowledge than me.
