What is the PAN-OS NPTv6 feature based on RFC 6296 used for?

The correct answer is B. IPv6-to-IPv6 network prefix translation. NPTv6 (Network Prefix Translation for IPv6), standardized in RFC 6296, performs stateless IPv6-to-IPv6 network prefix translation. It translates only the network prefix portion of an IPv6 address while leaving the host (interface identifier) portion unchanged, preserving end-to-e

Explanation

NPTv6 (Network Prefix Translation for IPv6), standardized in RFC 6296, performs stateless IPv6-to-IPv6 network prefix translation. It translates only the network prefix portion of an IPv6 address while leaving the host (interface identifier) portion unchanged, preserving end-to-end address transparency at the host level. It is used to map internal IPv6 prefixes to external IPv6 prefixes without maintaining per-flow state, providing address independence between internal networks and ISP-assigned prefixes. It does not perform port translation (A), is stateless not stateful (C), and does not alter the host portion (D).
