I can set up a mapping of any or all of those externally known networks with exactly one of my ULA networks, so, for example: So, for example, from Comcast I am assigned (currently) 2601:xxx:yyyy:5660::/60, and my ULA prefix is FD30:1839:ded::/48. This specification enables translating at the router between the globally routable designated prefix, and the ULA prefix described in the earlier post. G who is both smarter and less impetuous than I, found information in early April about a feature called NPTv6 or NAT66 Network Prefix Translation, RFC 6296. In particular there was a lot of hand-waving in trying to assign and maintain a separate network for the virtual machines on one of the interior boxes.Īt the end of March and into April I was grappling with writing scripts and trying to manage these difficulties, Mr. ![]() The implementation was pretty fragile, with a lot of unrelated bits in different places.This meant that I would have to figure out how to carry those patches forward in the event of firmware updates from Ubiquiti, the maker of the Edgerouter-X that I am using. The first implementation required that I make patches to the code of my router.And I don’t think it likely that my prefix would change unless some great catastrophe befalls which results in my being down for a very extended period – like 30 days or more likely there is some change in my service (a change in ISP, or perhaps fiber arriving in my area). Over the course of the last several months I have to note that Comcast has never changed my prefix, except early on, when I forced it to do so by changing my DUID. ![]() The biggest was the question how to handle the delegated prefix, particularly in renumbering.The main issue was that there remained a number of problems with the implementation of IPv6 in my residence. ![]() Since March 19th a great deal of what I wrote has been revised, as I have learned a lot more. This is a follow up to the activities in IPv6 implementation, which was published on March 2nd and revised up through March 19th, as new challenges were addressed.
