What is the primary purpose of NAT?
- **conserve IPv4 addresses ***
- allow peer-to-peer file sharing
- enhance network performance
- increase network security
NAT was developed to conserve IPv4 addresses. A side benefit is that NAT adds a small level of security by hiding the internal network addressing scheme. However, there are some drawbacks of using NAT. It does not allow true peer-to-peer communication and it adds latency to outbound connections.
