One of the reasons for lack of blog post publishing is that my attention has been focused fairly heavily on working within the IETF. Toward the beginning of the COVID pandemic, the US Government published a new initiative - M-21-07, which requires the migration of all federally owned systems to IPv6-only. What does “IPv6-only” mean, you may ask. Well, that’s kinda nebulous. People define it in varying levels of extremism, I’ve chosen to define it as “a device that can operate without the use of IPv4 configured”.

Over the last year there has been a slow hum, quietly building around the notion of building what has been called an “IPv6-mostly” network. What does this term mean? How do we do it? Why bother? Well, let me attempt to answer those questions. First, what is IPv6-mostly? Thankfully, it is pretty much what it sounds like - a network segment (i.e. a LAN segment) that is mostly IPv6, and only legacy IPv4 where it has to be.

IPv6 unique local addressing has been a popular topic over the years. From its humble beginnings, replacing site-local, to the surge of interest within service providers, enterprise, and casual users due to the wealth of content now available on IPv6 and the prevalence of availability within major consumer ISPs, it has become quite a polarizing topic in the technical communities that are diving head first into the modern, current networking protocol - IPv6.

Over the last few days there has been a huge amount of FUD and panic surrounding two as-yet-to-be-published CVEs (found here and here) related to Mikrotik’s IPv6 implementation.It is my opinion that this entire process has been poorly handled, and that the community involved tends to be fairly sensitive to issues such as, and the cloak and dagger nature of the two issues has only exacerbated it. Mikrotik, as a company, is well known for being terse in their responses and tight lipped with their internal workings and dealings with these kinds of issues.

IPv6 has been a crusade of mine for well over a decade. Wether it is teaching IPv6 workshops, offering advice to new users, answering questions, or evangelizing it ad nauseam, it is an important topic to me. The ISP world holds a special place in my heart since a good deal of my early experience came from building or assisting regional ISPs. Recently I had a fun opportunity to talk about deploying IPv6 on The Brothers WISP podcast.
