Checking your IP address (using `ipconfig` on Windows or `ifconfig` on macOS) ensures you have a valid IP address. A missing or incorrect IP address can prevent DNS resolution. The default gateway is your router's IP address; verifying it confirms your computer can communicate with your local network.
