A spreadsheet detailing every network and their static hosts for my new employer. Most of the hosts are already there but need to be reassigned to something more schema friendly, as I am about to connect everything together via VPN.

Part of this involves categorizing each subnet into criticality:
Production (high)
Office (medium)
Meh (low)

…as well as trust:
Trusted (such as engineering and dev)
OKish (Office and other production systems)
No!! (Semi-public wifi)
