I'm always surprised how few network guys are on HN.
Every device in infrastructure should have a management address. This int is routed differently than the data interface. In a datacenter, management will be a separate physical int but telecom can't go running 2 cables into a house so it's a logical management int in that case. Comcast remotes into my modem all the time for management purposes (service magically goes out) and I doubt they login via my DHCP address from them. It's just good practice to manage a device from a management int and in a consumer environment this should be hidden from the user. Everyone in infrastructure knows, the less the user knows the better.
Tinfoil hat time - funny cowinkydink they chose a DoD subnet. Why wouldn't they use 10.0.0.0/8 like the rest of the world? Could be them being different, could be something more. Convenient for the DoD to own the management subnet, just saying.
