Suggested Answer: Explanation 🗳️
So what is NPTv6? NPTv6 is simply rewriting IPv6 prefixes. If your current IPv6 prefix is 2001:db8:cafe::/48 then using NPTv6 it would allow you to change it to
2001:db8:fea7::/48 "" that is it.
It is a one for one prefix rewrite "" you can't overload it, have mismatching prefix allocations sizes, re-write ports or anything else. Importantly, it doesn't touch anything other than the prefix. Your network/host portion remains intact with no changes. http://www.howfunky.com/2012/02/ipv6-to-ipv6-network-prefix-translation.html
