[Getting the Most Out of IPv6
\----------------------------](https://www.paloaltonetworks.com.au/blog/2015/08/getting-the-most-out-of-ipv6/)

IPv6-to-IPv6 Network Prefix Translation (NPTv6) performs a stateless, static translation of one IPv6 prefix to another IPv6 prefix (port numbers are not changed). NPTv6 for IPv6 addresses is similar to NAT for IPv4 addresses. However, NPTv6 does not translate an entire IPv6 address; it translates only the prefix portion of the address. The host portion of the address is untranslated and therefore remains the same on either side of the firewall....
