Thedigcommand in Linux is used for DNS troubleshooting. It queries DNS records and provides detailed information about domain name resolutions.

traceroutetracks the path packets take to a destination but does not diagnose DNS.

netstatlists active connections, not DNS records.

ifconfigis used for managing network interfaces.

Awireless routeris designed to create an access point that allows wireless devices to connect to a network. It combines the functions of a traditional router with a wireless access point, enabling communication between wired and wireless devices. These routers use Wi-Fi standards (e.g., 802.11ac, 802.11ax) to transmit data wirelessly.

Broadband routersprimarily provide internet connectivity but do not necessarily include Wi-Fi functionality unless specified.

Core routershandle large-scale data routing in the backbone of networks but are not designed for access point creation.

Inter-provider border routersfunction at an ISP level for routing traffic between different networks, not for providing user access.

Configuring RADIUS authenticationenhances Wi-Fi security by requiring user authentication before granting access to the network. This prevents unauthorized users from connecting and mitigates risks from rogue access points.

WEPis outdated and insecure; WPA2/WPA3 with RADIUS should be used instead.

A bus topologyis a network design choice, not a security measure.

Avoiding asymmetric encryptionweakens security rather than improving it.
