I deal with lots of devices we put on customers networks. The problem is that 172.16.0.0/12, 10.0.0.0/8 and 192.168.0.0/16 are all used by customer networks. It's a pain when setting up VPN addressing. Thus I chose 11.0.0.0/16 (sadly not possible to use IPv6). My devices will never need to reach DoD, so that's very convenient.
