The impact here is that whoever currently controls the IP and keys will enumerate the IP addresses of about 0.7% of the users connecting to the network for the first time. They won't get to see any user traffic or user activity. I think this should be classified as "low severity", though I think our security policy may need clarification on the point.

Teor, I believe that this IP got removed as a fallback as I merged your fallbacks-201705-028 branch. Please let me know if that's not the case.
