ipv6 web server — how does ipv4 host in internet connect to it –options — stateless NAT64 with static ipv6v4 mapping, stateful NAT64 with static ipv6v4 mapping, NAT444, stateful NAT64
A. stateful NAT64 with static v6v4
B.
C.
D.
Correct Answer: A
Explanation/Reference:
– Stateless NAT64, defined in RFC 6145, is a translation mechanism for algorithmically mapping IPv6 addresses to IPv4 addresses, and IPv4 addresses to IPv6 addresses. Like NAT44, it does not maintain any bindings or session state while performing translation, and it supports both IPv6-initiated and IPv4-initiated communications.
– Stateful NAT64, defined in RFC 6146, is a stateful translation mechanism for translating IPv6 addresses to IPv4 addresses, and IPv4 addresses to IPv6 addresses. Like NAT44, it is called stateful because it creates or modifies bindings or session state while performing translation. It supports both IPv6-initiated and IPv4-initiated communications using static or manual mappings.
