Onavo Protect is a free and popular VPN owned by Facebook.

Facebook ostensibly uses Onavo to monitor user network traffic, specifically to gain insight into what is and isn't working in competing apps. That kind of sucks if you're building a consumer app and aren't planning on selling it to Facebook.

Detecting if the people who use your app are also using Onavo and encouraging them to disable it might be helpful to you.

Here is some Swift code that does that:

func checkForBadIP (_ ip: String) -> Bool {
