What does NAT stand for in networking terms?

• A. Near Address Transfer
• B. Network Allocation Token
• C. Network Address Translation
• D. Node Address Translation

Answer: (C)

NAT stands for Network Address Translation. It’s the process routers use to modify IP addresses as packets move between a private network and the public Internet. This lets many devices with private IP addresses share a single or few public IPs, conserving IPv4 addresses. The router keeps a translation table that links each internal private address (and port, if needed) to a public address (and port), so responses find their way back to the correct device. NAT can work in several modes, such as one-to-one static mapping, dynamic mapping from a pool of public addresses, or port address translation (often called NAT overload) where many internal hosts share one public IP by using different ports. While NAT hides internal addresses and supports broader connectivity, some protocols or applications that assume end-to-end addressing can encounter issues unless NAT traversal techniques or configuration (like port forwarding) are used. The other terms listed aren’t standard networking terms for this concept.
