Network connectivity service — manages system network status and reachability monitoring

Monitors network interface states and connectivity changes across Wi-Fi, Ethernet, and cellular connections. Communicates reachability status to client applications through XPC or distributed notifications, enabling them to adapt behavior based on network availability. Contacts multiple external endpoints to validate actual internet connectivity rather than relying solely on interface state. Runs as a system daemon to provide unified network status information across the platform.AI
