NAT (Network Address Translation) and VPN (Virtual Private Network) serve different purposes. NAT translates private IP addresses to a public IP, enabling multiple devices to share one IP address. Conversely, a VPN encrypts internet traffic and hides the user's IP, providing privacy and security. While NAT facilitates efficient network management, a VPN ensures secure and private communication.
