Which methods of deployment can you use when implementing NAT64?

A. stateless
B. stateful
C. manual
D. automatic
E. static
F. functional
G. dynamic

While stateful and stateless NAT64 perform the task of translating IPv4 packets into IPv6 packets and vice versa, there are important differences. The following table provides a high-level overview of the most relevant differences.

Differences Between Stateless NAT64 and Stateful NAT64

Stateless NAT64Stateful NAT64
1:1 trtanslation1:N translation
No conservation of IPv4 addressConserves IPv4 address
Assures end-to-end address transparency and scalabilityUses address overloading, hence lacks in end-to-end address transparency
No state or bindings created on the translationState or bindings are created on every unique translation
Requires IPv4-translatable IPv6 addresses assignment (mandatory requirement)No requirement on the nature of IPv6 address assignment
Requires either manual or DHCPv6 based address assignment for IPv6 hostsFree to choose any mode of IPv6 address assignment with Manual, DHCPv6, SLAAC
