A medium$-$sized enterprise has recently expanded its operations, resulting in a significant increase in the number of employees. The company's network now includes over $200$ devices that require internet access.

The enterprise has been allocated a small pool of public IP addresses by their Internet Service Provider $($ISP$).$ The network administrator needs to configure a NAT solution that allows all devices to access the Internet without assigning a specific public IP address to each device.

Which type of NAT should the network administrator implement to meet these requirements?

Port forwarding

Static NAT

Dynamic NAT

Port Address Translation $($PAT$)$
