Which of the following refers to a process of modifying an IP address to allow the device to become hidden and only accessible on a private network?

WPS (Wi-Fi Protected Setup) is a wireless standard designed to simplify the process of connecting devices to a secure wireless network and does not involve IP address translation.

MAC filtering controls network access based on hardware addresses and does not modify or translate IP addresses.

DHCP dynamically assigns IP addresses to devices on a network but does not translate or hide addresses from external networks.

NAT (Network Address Translation) is a process performed by a router that maps private, non-routable internal IP addresses to a single public IP address when communicating with the internet. This makes internal devices invisible and inaccessible from outside the private network, as they have no directly reachable public IP address.
