NAT is a form of network address translation that allows multiple devices on a local network to share a single public IP address. This is done by translating the private IP addresses of the devices on the local network to a single public IP address when they access the internet. NAT is used to conserve IPv4 addresses and to provide security for devices on the local network.
NAT is an important part of the internet infrastructure. It allows multiple devices on a local network to share a single public IP address, which conserves IPv4 addresses. NAT also provides security for devices on the local network by hiding their private IP addresses from the internet.
