However, all three apps make a Domain Name System(DNS) request to the computer hosting the WiFi network to resolve the IP address of "www.dji.com" when they are first started. This DNS request goes to the router or a DNS server, and does not actually communicate with any DJI servers, but it does tell the app the IP address of DJI servers. The DJI Pilot Beta app follows this DNS request up with a ping to one ofthe DJI servers, and receives a ping response back. This ping is used by the app to check that the server is up and can receive messages. The ping does not contain any data, but the server could get the IP address of the tablet and the time the app was started (since that’s when the ping is sent)
