There are a few ways to find the subnet mask on Android. The first way is to use the network information tool in your Android device’s settings. This tool allows you to see all of the networks that are connected to your device and their associated IP addresses. You can then use this information to find the subnet mask for a specific network. The second way is to use a computer or phone with an internet connection and look up the IP address of the network that you want to connect to. This method is more difficult and requires some knowledge about networking devices and how they work.
