The Home Lab Workbench
What is on your network, which address it has, where it sits in the rack and what it draws — with the rack diagram, the host file and the DHCP reservations to take away.
Units: Metric US
Addressing
Your subnets and VLANs. Overlaps are caught here rather than at two in the morning when two things answer to the same address.

Hosts and services
What holds each address and which ports it answers on. An address outside its subnet, or claimed twice, is flagged.

Rack and power
What sits at which U, and what the whole thing draws against the circuit feeding it.

Print and export
A rack elevation to print, a hosts file, DHCP reservations, CSV, and a backup of the lot.

Everything here stays in this browser. That is the right default for a network diagram — it is a map of what you run, which ports are open and where the gaps are, and the safest place for that is not somebody else's database.
Clearing your browser data clears it, so export a backup.
