''' Notes '''
* On Android 7.0 (API 24) and above, the trigger uses the NetworkCallback API for efficient network monitoring.
* On older Android versions, the trigger monitors the CONNECTIVITY_ACTION broadcast.
* The trigger compares the new IP address with the previous one and only fires if there's an actual change.
* The trigger will not fire if the IP address cannot be determined (shown as "?").
* The previous IP address is stored in settings to detect changes across app restarts.
* The trigger fires for IPv4 address changes.
''' Use Cases '''
* Updating dynamic DNS services when your IP changes
* Notifying external services of your new address
* Logging network changes for troubleshooting
* Triggering reconnection logic when network changes
