The network team is reviewing its options with regard to network address translation. Now that the network has been completely changed over to IPv6, you need a mechanism to translate from the private IPv6 addresses inside your network to public IPv6 addresses. You would like for these mappings to be one-to-one.

The network team is reviewing its options with regard to network address translation. Now that the network has been completely changed over to IPv6, you need a mechanism to translate from the private IPv6 addresses inside your network to public IPv6 addresses. You would like for these mappings to be one-to-one.

Which of the following performs this function?

  • stateful NAT64
  • NPT6
  • NAT44
  • stateless NAT 64
Explanation:
NPT6 is a version of NAT that translates private IPv6 addresses to public or global IPv6 addresses. It is a stateless mechanism and requires a one-to-one mapping of private to global IPv6 addresses.

Neither version of NAT64 translates from private IPv6 addresses to public or global IPv6 addresses. Both stateful and stateless NAT64 translate from IPv4 to IPv6.

NAT44 does translate private IPv6 addresses to public or global IPv6 addresses, but it is stateful in operation. It does not perform one-to-one mappings.
