Network Address Translation (NAT) is a method used in networks to modify network address information in IP packet headers while in transit, allowing multiple devices on a local network to share a single public IP address. This process enhances security and conserves the limited number of available IPv4 addresses by hiding the internal IP addresses from external networks.

A local network, often referred to as a Local Area Network (LAN), is a group of connected devices within a limited geographic area, such as a home, office, or building, enabling resource sharing and communication. It typically uses Ethernet or Wi-Fi technology to connect computers, printers, and other devices, facilitating efficient data exchange and internet access within the networked environment.

A public IP address is a unique identifier assigned to a device that enables it to communicate over the internet, allowing it to be located and accessed by other devices globally. These addresses are managed by the Internet Assigned Numbers Authority (IANA) and are essential for routing internet traffic effectively and securely.
