The real official answer to this is to register/allocate a new subnet, with no intention of putting it into the global routing tables. IPv6 only comes into play because doing that with IPv4 is mostly impractical these days.
The author lost me when they got into raw iproute commands - if someone knows enough to configure things at this level, then they would just come to this solution on their own. Most people trying to solve this problem will not - eg think that mobile video rack belonging to a touring musician.
More readily-accessible solutions I can come up with:
1. Two off the shelf routers and double NAT. The middle network can be changed if it conflicts with the outer network
2. One router/NAT, but two IP networks on the inner network - one statically assigned for devices to communicate with each other, and one assigned via DHCP for accessing the horizon through NAT. That second network can then easily be changed.
3. Play battleship more strategically using class D/E address space, DOD/BigCo address space, and/or smaller subnets in the middle of a customary range (ie 192.168.1.160/27).
As a network engineer it was interesting to read about VRFs and routing from the perspective of an A/V engineer. Thanks
