The home segment moves off 192.168.1.0/24

Browse Source 
It is the commonest home LAN range there is, so on an ordinary workstation the
lab's private segment and the machine's own network are the same addresses. The
scenario routes an egress machine explicitly and marks the rest unreachable, so
nothing leaked — but that guard was carrying the whole weight of a collision
nobody chose, and a guard is a bad place for that.

10.99.1.0/24 is still RFC 1918, so the bed still models a home LAN behind an
access point. It is simply far from what this kind of machine already has:
192.168.1 is the LAN, 172.16-31 and 192.168.16-95 are container bridges, and
10.10/10.42/10.208 are a tunnel, the mesh overlay and the virtualisation daemon.
