What is an advantage of deploying IPv4 NAT technology for internal hosts in an organization?

  1. increases the performance of packet transmission to the Internet
  2. makes internal network access easy for outside hosts using UDP
  3. **provides flexibility in designing the IPv4 addressing scheme ***
  4. enables the easy deployment of applications that require end-to-end traceability

IPv4 NAT provides some benefits:
– NAT conserves the legally registered addressing scheme.
– NAT increases the flexibility of connections to the public network.
– NAT provides consistency for internal network addressing schemes.
– NAT provides certain level of network security by hiding the internal network topology and hosts.

IPv4 NAT also brings some disadvantages:
– NAT may impact the network performance due to the translation process
– End-to-end addressing is lost, especially when dynamic NAT is used.
– End-to-end IPv4 traceability is also lost.
– NAT complicates tunneling protocols, such as IPsec.
– Services that require the initiation of TCP connections from the outside network, or stateless protocols, such as those using UDP, can be disrupted.
