To check if NAT: Open the Command Prompt (Windows) or Terminal (Mac). Type `ipconfig` (Windows) or `ifconfig` (Mac) and note your IP address. Then, search 'what is my IP' on a browser. If the IP addresses differ, you are behind a NAT (Network Address Translation). This indicates that your local network is masking multiple devices under a single public IP address, enhancing security but possibly complicating direct IP-based communications.
