These operating systems do not allow applications to fetch local IP information, which prevents the posture check from evaluating the device's network range. + +**Affected platforms:** +- iOS +- Android + +**Impact:** + +When a policy with a Peer Network Range posture check is applied to mobile clients, the check cannot be evaluated. This may cause routes to become unavailable on these devices, even when the device is outside the blocked network range. + +**Recommendation:** + +If your deployment includes iOS or Android clients, consider one of the following approaches: + +- Create separate policies for mobile clients that do not include Peer Network Range posture checks +- Use alternative posture checks (such as Geo Location) that are supported on mobile platforms +- Apply Peer Network Range posture checks only to policies targeting desktop platforms (Windows, macOS, Linux) + ## Get started with NetBird
