I think Icomera’s bus WiFi systems also use 1.1.1.1 somewhere in the hotspot process.

TBH, I’m not surprised, and this definitely isn’t the first time something like this has happened. For example, Hamachi (before being bought by LogMeIn) squatted on 5.0.0.0/8, and then (when 5.0.0.0/8 got allocated) on 25.0.0.0/8 (which was already allocated to the British MoD).

This is really nothing new, and now that I think of it, not really surprising!
