In a wireless security investigation, determining the gateway IP helps identify which device?

• A. The gateway will be the IP used to manage the access point
• B. The gateway will be the IP of the attacker computer
• C. The gateway will be the IP of the proxy server used by the attacker to launch the attack
• D. The gateway will be the IP used to manage the RADIUS server

Answer: (A)

The gateway IP on a wireless LAN identifies the device that routes traffic from the local network to other networks, typically the access point or the router that sits at the network edge. Because devices on the LAN use this address as their default gateway, the gateway IP is effectively the management URL for the device that controls wireless traffic and network access. In practice, finding this IP allows you to identify the device you’d log into to configure the AP, review logs, and check settings, which is central in a wireless security investigation. The other options don’t fit because the gateway address represents the network’s edge device, not a specific attacker workstation, a proxy server used in an attack, or a separate RADIUS server management interface.
