Re: Been through this myself.
It's usually more prosaically annoying than that.
IT charge 250quid and take 2-4 weeks to provision a network port, so labs become a nest of cheap of cables connecting cheap supermarket 4port desktop switches to the one official port in the corridor outside.
Or you need to keep an old windowsXP machine on the net because it has a card to talk to some 10year old experiment. But IT only allow a standard Windows10 with all ports locked down and no admin so your experiment now has a grad student making a homebrew HID emulator on a Pi to 'type' in the results
