    It is a method of remapping one IP address space into another by modifying network address information in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic routing device.

    • Network address translation (NAT)

    • Port address translation (PAT)

    • Subdomains

    • IP addresses assignments

    Correct Answer
    A. Network address translation (NAT)
    Explanation
    Network address translation (NAT) is a method used to remap one IP address space into another by modifying network address information in IP datagram packet headers while they are in transit across a traffic routing device. This allows multiple devices on a local network to share a single public IP address, conserving the limited supply of IPv4 addresses. NAT works by translating the private IP addresses of devices on the local network into a single public IP address when communicating with devices on the internet, and vice versa. This helps to improve network security and manage IP address allocation efficiently.
