Stateful NAT64 specifications?(Choose three)
A. 1:N translation
B. Conserves IPv4 address
C. Uses address overloading, hence lacks in end-to-end address transparency
D. State or bindings are created on every unique translation
E. No requirement on the nature of IPv6 address assignment
F. Free to choose any mode of IPv6 address assignment viz. Manual, DHCPv6, SLAAC
Correct answer are all
Stateless NAT64
– 1:1 translation
– No conservation of IPv4 address
– Assures end-to-end address transparency and scalability
– No state or bindings created on the translation
– Requires IPv4-translatable IPv6 addresses assignment (mandatory requirement)
– Requires either manual or DHCPv6 based address assignment for IPv6 hosts
Statefull NAT 64
– 1:N translation
– Conserves IPv4 address
– Uses address overloading, hence lacks in end-to-end address transparency
– State or bindings are created on every unique translation
– No requirement on the nature of IPv6 address assignment
– Free to choose any mode of IPv6 address assignment viz. Manual, DHCPv6, SLAAC
ALL CORRECT
