The Home Network Map: Write It Down Once

A printable for recording every device, cable and address on your network, so the next outage is a five-minute job instead of a whole evening.

Every home network is documented in exactly one place: the head of whoever set it up, on the day they set it up.

That knowledge decays fast. Six months later even the person who built it is following cables by hand to find out what a device does.

What goes on the sheet

Every device with a name, an address, what it is for and where it physically lives. The router’s ports, numbered, with what is in each one. And the small print nobody remembers: which socket the fibre comes into, what the admin password is stored in, and which switch has the fan that is about to fail.

The change log is the useful part

Three lines each time you change something: what you did, when, and why. In two years that column is the difference between an odd setting being a mystery and being a decision you made for a reason you can still read.

Where it lives

Printed, in a folder, in the cupboard with the router — not in the notes app on the phone that cannot reach the internet because the network is down. The whole point of this sheet is that it works in exactly the conditions where your other records do not.

What you get

A device table: name, address, what it does, where it physically is
A port map for the router and every switch, so unplugging is not a guess
A change log — three lines that explain why the network is like this
A one-page outage drill for when nothing works and everyone is looking at you

Questions

Because the moment you need it most is the moment the network is down, and the device holding the information is on the network. Paper in the cupboard with the router is readable during an outage, during a power cut, and by whoever is home when you are not.

Yes, and it takes about fifteen minutes to fill in. Simple setups still have the same problem: nobody remembers which of the four identical black boxes is the modem, or which socket the one important cable goes in. The complexity that hurts is not scale, it is elapsed time since you set it up.
