@jtk@infosec.exchangeNew (very minimal) Internet-Draft submitted: ASN Prefix-based Addressing for IPv6
"This document describes a method and policy for ASN prefix-based addressing for IPv6."
If this goes anywhere I expect it will change, and grow, markedly.

@thek3nger@mastodon.socialTIL: AirPlay stopped working on macOs Tahoe.
Solution: System Settings > Wifi > click "details" next to your wifi network > select TCP/IP tab. Change "Configure IPv6" setting from Off to "Link-Local Only".
🤷♂️ No effing idea why.
@marcus@hachyderm.ioI would also like #ipv6 to be adopted. However my ISP doesn't even give me a ipv6 allocation, so had to set up a tunnel over tunnelbroker.net. My learnings so far; some of this stuff specially related to dynamic ip allocation isn't that trival to understand. https://www.apalrd.net/posts/2023/network_ipv6/
@hakona@im.alstadheim.noHad some weird issues with my instance just now. Random stuff stopped working. Turns out my instance had only ipv6 connectivity, not ipv4. Reading worked mostly, but random stuff would fail, did not trigger my intuition as to where the error lay.
In hindsight, it was probably any direct fetch form instances with only ipv4 connectivity that failed. Posts that got sent on from or via elsewhere showed up, so it was not immediately obvious.
@jtk@infosec.exchangeIf you don't see the real reason for IPv6, I guess we don't have much else to say to one another?

@penguin42@mastodon.org.ukSubmitted an IPv6 ticket to my ISP, #youfibre - as far as I can tell inbound packets are fine, outbound IPv6 don't seem to get far.
They were working a few weeks ago when I started doing IPv6 config on my router; but there's plenty of other people saying they've had IPv6 problems with them intemittently.
@gwire@mastodon.socialOne thing I hadn't seen, prompted by their network outage yesterday, is how much better the IPv6 situation has developed on Vodafone in the last two years. Up to 75% now.

@aral@mastodon.ar.alJust added Web Reachability API (at least that’s what I’m calling it) support to https://ip.small-web.org.
It’s for testing the reachability of your Small Web servers (using a domain or, more importantly, an IPv4/IPv6 address). I’m using it to implement Web Numbers¹ support in Auto Encrypt² and Kitten³.

@gpummer@t.testitfor.meIch habe heute meinen virtuellen Root-Server von Ubuntu 20.04 auf 22.04 aktualisiert. Ja ich weiß, dass ich spät dran bin:)
Blöd, wenn das do-release-upgrade mit einer Fehlermeldung abbricht, dass jammy.tar.gz nicht gefunden wird. Weil die IPv6 Webserver von ubuntu.com ein Problem haben. Mit den IPv4 Servern gehts. (/etc/hosts hilft) Argl!
Megablöd, wenn dann bei ca. 60% des Updates kein Platz mehr auf der Platte ist. Mega Argl!
Gut, dass es jetzt trotzdem läuft. \o/
@grifferz@social.bitfolk.comIPv6 on average ~2ms lower latency than IPv4, and has been pretty much since 2015.
There are many reasons why, including things like usually on newer equipment, and no CGNAT.
Sometimes counter-intuitive as IPv6 headers are larger than IPv4 ones.

@grahamperrin@bsd.cafe@… I can't tell whether you're joking.
No IPv6 at home in my region and when I last checked, no IPv6 at work.
I don't imagine gaining IPv6 during or before 2029. No joke.
#FreeBSD
@chrysn@chaos.socialWe're doing a bad job adulting with IPv4-curious ISPs. Maybe we should adopt the "This is not a place of honor" mem instead?
#IPv6
@jtk@infosec.exchangeSomewhat surprised to discover that as of now, from my vantage point, akamai.net's NS RRset of 13 names only two are #IPv6-enabled.
@grumpybozo@toad.socialI would bet a beer on that being not entirely true.
I have no doubt that I could disable IPv4 with a small number of sysctl commands. (which are not obviously designed for that end…) https://wirebug.ch/beni/p/1754635541.104285
@whitequark@mastodon.sociali guess i'm getting an ASN and some IPv6 PI space
@wyri@toot-toot.wyrihaxim.us@… CloudFlare? I also need to get IPv6 fully up and running on my cluster because those queries still escape adblocking 🤦♂️
@jtk@infosec.exchangeYou might be an anti #IPv6 kook if...
@grahams@mastodon.socialI've apparently reached "Figure out IPV6 for my network" levels of unemployment.
So if you need a software engineering manager or something else vaguely me-shaped, hit me up.

@penguin42@mastodon.org.uk'iptraf-ng' is a TUI network monitor; it's a really easy way of watching bandwidth on each of your interfaces, and has modes to split between say IPv4/IPv6/TCP/etc, or packet size; and shows you all the IP connections currently transferrign thing, or all the ethernet devices currently doing stuff.

@whitequark@mastodon.socialQ: how do you use NixOS if your environment is IPv6-only? eventually you encounter some non-binary-cache package that downloads shit from github for no reason and you're fucked, right?
@grifferz@social.bitfolk.comI've been distrustful of Docker for so long that I've never really got into using containers. I get very confused by how it takes over the networking and needs to add and remove its own firewall rules. They clash with my use of nftables, and IPv6, and my other automation. It's made me avoid it.
But Podman has really been coming along and I've been looking at it again. It's going quite well.

![Establish BGP session and configure routing
To use the anycast addresses, you need to establish a BGP session. A specific node can be connected to a single AnycastIP router (IPv4 and IPv6 session) at a given time. You can have multiple nodes per region - all our routers support ECMP.

2. Get the IP addresses of our router in the given region (see below) and configure BGP sessions using the following deta…](https://files.mastodon.social/media_attachments/files/115/312/456/718/850/223/original/5041c397bb71f4b3.png)
