• To map a public IP address to multiple private IP addresses

• To provide local hosts access to the Internet by translating private IPs to public IPs

• To assign private IP addresses to Internet devices

• To prevent the usage of public IPs

• Connecting multiple devices

• Network security

• Wireless network extension

What does Dynamic NAT require to function?

• A list of port numbers

• A pool of public IP addresses

• A single private IP address

• Static IP configurations

What is PAT also known as?

• Dynamic NAT

• Port Address Translation

• Static NAT

How does PAT handle multiple private IPs with a single public IP?

• By using different private IPs

• By assigning unique port numbers

• By using a pool of public IPs

• By creating separate routes

Which NAT configuration is commonly used in home routers?
