Routing Information Retrieval: Obtains system routing table information, particularly default gateway information
Firewall Rule Query: Retrieves firewall chain and rule information through iptables
Network Process Association: Obtains information about processes occupying network ports
Network Configuration Query: Retrieves network configuration information such as hosts file and resolv.conf
Network Interface Detection: Detects network link types (Ethernet/WiFi), link status, etc.
WiFi Information Retrieval: Obtains wireless network interface information including operating mode, frequency, channel, and rate
DHCP Configuration Query: Retrieves IPv4 and IPv6 DHCP configuration information
