From The Grid to Cloud Heights
Mission 01 — Know Your Neighborhood
Walk Ivy's four deliveries to where they actually go: the ones inside the 10.20.5 block, and the ones that have to leave through the gateway.

Ivy says: This is my block. My van is at 10.20.5.42 and the mask is /24 — so every address that starts 10.20.5 is a building I can walk to.
Ivy says: Four deliveries on the work order. Before you send me anywhere — guess which ones are on this street.

Addresses 10.20.5.1 – 10.20.5.255

Drop the replacement toner at 10.20.5.20.
10.20.5.20
Pick the place in the neighborhood that matches the address on Ivy's work order. If it isn't on this block, send her to the gateway road. Nothing is locked in — try any route and watch what happens.
For this /24 example, addresses that share 10.20.5 are in the same neighborhood. Other masks split the address differently — that comes later.
