Understanding NAT Methods
Network Address Translation (NAT) is a technique used in networking to manage IP address allocation. Here are the primary methods of NAT:
1. Static NAT
- This method maps a private IP address to a public IP address.
- It is typically used when a device needs a consistent public IP address, such as a web server.
2. Dynamic NAT
- Dynamic NAT uses a pool of public IP addresses and assigns them to devices as needed.
- It is efficient for networks with many devices but limited public IPs.
3. NAT Overload (PAT)
- Also known as Port Address Translation, it allows multiple devices on a local network to be mapped to a single public IP address.
- This method uses different ports to differentiate between devices, enabling efficient usage of IP addresses.
4. Double Translation
- This involves translating an address twice, which can complicate the routing and is generally not recommended.
5. NAT IP Pool
- Similar to dynamic NAT, it uses a predefined pool of IP addresses to assign to devices dynamically.
Why Option C is Correct
- Static NAT (1)
- Dynamic NAT (3)
- NAT Overload (5)
These three methods effectively represent the core functionalities of NAT. Options 2 (Double Translation) and 4 (NAT IP Pool) are either less common or merely variations of the primary methods, thus confirming the answer as option 'C'.
In summary, option 'C' includes the essential NAT methods: Static, Dynamic, and Overload, which are crucial for efficient IP address management in networking.
