But when you're seeing the same session being used from two wildly different places (in this case, IPv4 and IPv6) at the SAME TIME, that does seem rather suspicious in the absence of other information.
iOS 9 has a new feature called "Wi-Fi Assist" that will "automatically use cellular data when Wi-Fi connectivity is poor". This will most likely cause those pesky IP checks to fail (even if you use a /24 or AS check). Geolocation checks will also fail in some cases. My geolocation when connected to WiFi and when using cellular data are widely different. WiFi reports the city I'm in while cellular reports the city that their HQ is in. -- “Simply stated, we have a new formula for Coke.” --- Roberto C. Goizueta, Company Chairman, Coca-Cola
