Network Address Translation (NAT) allows multiple devices on a private network to access the internet using a single public IP address. This is crucial for conserving IP addresses and for allowing an entire network to communicate to the outside world using a simple, singular address. NAT modifies the IP addresses of outgoing packets from a private network to appear as though they are originating from the router’s public IP address to external hosts. The other options describe different technologies or concepts that are not directly related to the specific function of NAT.
