What is the primary purpose of NAT?

  1. **conserve IPv4 addresses ***
  2. allow peer-to-peer file sharing
  3. enhance network performance
  4. increase network security

Explanation:
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.
