What is Port 2196?
Port 2196 was used by Apple Push Notification service (APNs) feedback service, which provided app developers with a list of device tokens for which push notifications failed. Developers would query this service to remove invalid device tokens from their databases. This legacy interface has been replaced by the HTTP/2-based APNs provider API.
