NPTv6 stands for Network Prefix Translation and like NAT it allows the translation of IPv6. The difference, however, is that NPTv6 only translates prefixes. It doesn’t translate the host address, there is no “overload” like NAT where you can have multiple source addresses behind a single address. It’s a simple 1:1 translation for prefixes.

I've written previous posts on NPTv6 but it seems I didn't do a particularly good job explaining the different between NPTv6 and NAT66 and ...

IPv6-to-IPv6 Network Prefix Translation draft-mrw-nat66-08. Abstract. This document describes a stateless, transport-agnostic IPv6-to-IPv6 Network Prefix Translation (NPTv6) function that provides the address independence benefit associated with IPv4-to-IPv4 NAT (NAPT44), and in addition provides a 1:1 relationship between addresses in the "inside" and "outside" prefixes, preserving end to end ...

13.11.2020 · The NPTv6 support on ASR1k/CSR1k/ISR4k is an algorithmic translation function which provides a 1:1 relationship between the addresses within the inside and outside network. When NTPv6 is used, you can interconnect different networks and support multihoming, load balancing, peer-to-peer networking.

10.12.2013 · NPTv6 is different then NAT66 in that only the leftmost prefix portions of the address are translated. This means that the device doing …

NAT66 is used for translating an IPv6 source or destination address to a different IPv6 source or destination address. NAT66 is not as common or as important as ...

While I am pretty firmly in the IPv6 camp of no NAT66 and limited NPTv6 use I do understand there are times where those can be appealing to ...

NAT66 (NPTv6) ¶ NPTv6 is an address translation technology basedon IPv6 networks, used to convert an IPv6 address prefix in an IPv6 message into another IPv6address prefix. We call this address translation method NAT66.

On the other hand, IPv6 renumbering is not so bad compared to IPv4. ... NPTV6#show nat66 prefix Prefixes configured: 1 NAT66 Prefixes Id: 1 ...

NPTV6(config)#nat66 prefix inside 2001:DB8:0:12::/64 outside 2001:DB8:0:2::/64. The inside prefix is the link that we use between H1 and NPTv6, the outside prefix is the one on the loopback 0 interface. That’s all we have to configure. Verification. There are only two show commands. Here’s the first one:

Dec 10, 2013 · NPTv6 is different then NAT66 in that only the leftmost prefix portions of the address are translated. This means that the device doing this translation do not need to keep state at all. So NPTv6 is stateless and therefore in theory can scale better and also be distributed across many devices doing the same function (regardless of forwarding ...

NPTv6 performs stateless translation of one IPv6 prefix to another IPv6 prefix. It is stateless, meaning that it does not keep track of ports or ...
