The combination of occasional GPS/Wifi location data and continuous IP data is pretty powerful though.

There's a setting hidden away in android allowing apps to scan local wifi/bluetooth networks even when wifi is turned "off". Enabled by default of course.
What settings is that?
Settings > Location > Improve Accuracy

2 settings, one for Wi-Fi scanning and one for Bluetooth

Security & Location -> Privacy -> Location -> Scanning

(Supposedly; I don't own an up-to-date Android device.)
