WAS. As was I. Straws that broke my back finally were not being able to get a static IPv6 address out of comcast, my hurricane tunnel getting blocked by netflix, the still-huge prefix sub-distribution problem. The idea of dynamic 2 week prefixes in part of the world prone to earthquakes doesn't work for me... and my email over ipv6 is perpetually getting blocked. spamhaus blocked multiple attempts to get dave at taht.net (fully ipv6 enabled) to send mail ti this list. And I sat on it for an hour after clearing it, in the hope the block would clear. It didn't. Getting off email blocklists isn't a problem users can handle... and spamhaus has no means of interacting with me. I *really* wanted email right to my servers in my office to just work, over ipv6. Everywhere I've been lately (nicaragua, portugal) has switched to whatsapp. Damn it, I wanted ipv6 to roll out faster than it has. I'm in a half dozen RFCs, worked in IETF homenet, founded the cerowrt project with an explicit goal of making ipv6 more deployable (as we did!), *by actually implementing and distributing* more code based on the standards, and I plan to keep working on making ipv6 better, but that said, we need more running code, still, which only then can get into a deployment, and nobody's funding that. Nobody's implemented much of ietf homenet. there's no code to enable prefix distribution on android. those are my top two ipv6 bullet items. more universal SADR would help. Tunnels of all types "just working" would be good too. Perhaps with the chinese government mandating more ipv6, more open source code, at least, will get funded and written. Maybe not of the freedom and privacy enhancing stuff, though. > > >> But Mr.Rey's reference about IPv6 deployment rates also makes a good point! > > Nobody cares about deployment rates.

One entertaining thing I've been up to is checking the state of multiple kinds of deployment in the coffee shops of the world with a string of simple tests anyone can do (after we package them up better) https://lists.bufferbloat.net/pipermail/bloat/2019-September/009334.html So far thats: Bufferbloat: 95% (starbucks is doing the right thing here, yea!) IPv6: 0% DNSSEC: 0%. "coffee shop testing" offers y'all the opportunity to go "fix it" by leaping over the counter, and/or to get a deeper grip on the real deployment problems we have with middleboxes along the edge. Sometimes leads to free coffee, too! Please have more meetings in coffee shops, not conventions! Does anybody here, know what the heck the 5G people plan to do with IPv6? and new places like starlink and oneweb and the like? I really hope the 5G folk are going to get ipv6 prefix distribution and SADR right, but have no data. > >> We also have to acknowledge "IPv4 zealots" are real. > > And they are the ones with the money.

I should make clear I'm not a zealot of any sort on the ipv4 vs ipv6 front. (I freely confess to being zealous about fq_codel... but if you deployed it and looked at the data, I figure more would become one also! :)) I came to the reluctant conclusion last year that dual stack is going to be ~forever, that ipv6 was platauing in multiple ways and we needed to kick it harder, that the rollout stats vs actual usage were hopelessly overoptimistic... and went poking at what we could do to ALSO make ipv4 better as a third way out and have been plunking away it ever since. One thought was: Since there was demand for more IPv4, perhaps that would also fuel more updates to ipv6, as both require middlebox updates... As for money to make middleboxes better in *any* way, don't make me laugh. During the cerowrt project we approached everybody making money from the internet and multiple non-profits and got nowhere. I spent my own fortune on it, and got a lot of volunteers onboard, especially in the openwrt universe... and made things better, but I got nothing left. We need a new kame-like project to jointly handle the cracks in the ipv6 network architecture, standards and code, at the very least. The costs of "mo ipv4" are trivial in comparison. > 3 months ago, I turned DECNET off on my network.

We run OS/2 Warp, MS-DOS, Windows 95, HPUX, Solaris, Windows > 2000, and I probably forget some. Please note the ipv4 extensions stuff won't work with most that "legacy" ipv4 stuff. It can, however, enable new applications and services to exist. Most of the IOT and SDN stacks already do work. Most don't have decent ipv6 support due to resource constraints. Perversely I kind of like the idea of a portion of the internet immune from legacy windows worms and viruses.... > > In 20 years, I will still need IPv4.

We cited that work in our presos on this subject as that was also key on gilmore, paul wouters and myself to start looking hard at what it would take to make ipv4 better in multiple ways. Please look it over!? The ipv4 unicast extensions project is one outgrowth of that: A string of trivial patches to a couple OSes and routing daemons and we're well on our way to being able to add 420m new addresses to the internet, within a 10 year time horizon. Politically... oh, lawd. I'm focusing on technical feasibility only at the moment. If you want some details about that, see the WIP here: https://github.com/dtaht/unicast-extensions/tree/master/rfcs I'd like lots more folk to review this before we punt it up to iana and the ietf, the RIRs and so on, and more to fiddle with 240/4 and 0/8, at least. Pay special attention to section 7.1. There's more than just this to make ipv4 better, possible. Taking flack on just this much is no fun, but can we get more folk thinking out of this box in general? We certainly aren't proposing that ipv6 wg's *disband* but if more folk would focus on making the code work and implementing more of the standards that exist, AND looking at deployment problems with an open mind and willingness to get in there and fix them, that would be a goodness. -- Dave Täht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740
