Which of the following IPV6 transition technologies are address translation technologies? (Multiple choice)

Question

Options

• ANAT64
• BIVI
• CDual stack
• D6PE

• A
  71% (49)
• C
  9% (6)
• D
  20% (14)

Explanation

NAT64 and IVI are both address translation technologies because they actively convert between IPv4 and IPv6 address formats, allowing communication between hosts using different IP versions. NAT64 maps IPv6 client addresses to IPv4 server addresses at the network boundary, while IVI (a stateless translation mechanism) embeds IPv4 addresses within IPv6 addresses using a defined mapping algorithm - both fundamentally translate one address format into another.

Dual stack (C) is wrong because it doesn't translate anything - it simply runs both IPv4 and IPv6 natively on the same device simultaneously, requiring no conversion. 6PE (D) is wrong because it's a tunneling technology, not a translation technology - it encapsulates IPv6 packets within IPv4 MPLS networks to carry IPv6 traffic across an IPv4 backbone without address conversion.

Memory tip: Think "translation = transformation of the address itself." If the technology changes an IP address from one version to another (NAT64, IVI), it's translation. If it wraps packets without changing addresses (tunneling like 6PE) or supports both without converting (dual stack), it's not translation.
