What is the role of “NAT” in networking?
a) Translates private IP addresses to public IP addresses
b) Encrypts data on a network
c) Monitors network performance
d) Manages user accounts on a network
Answer:
a) Translates private IP addresses to public IP addresses
Explanation:
NAT (Network Address Translation) is a technology that translates private IP addresses used within a local network into public IP addresses, which are required for communication on the internet. This allows multiple devices on a private network to share a single public IP address.
NAT is commonly implemented in routers and helps improve security by masking the internal IP addresses of devices on a local network, making it more difficult for external threats to target them directly.
By using NAT, organizations can conserve public IP addresses while maintaining internet connectivity for all devices within the private network.
