First draft of a script that seems to do what I want: https://dpaste.org/SCAQ7 (expires in 1 week, since I'll probably be tweaking the code)

I put #IPv6 resolvers before IPv4 because it's right and to hell with what Lenny says.

Grabbing the information per interface means one could potentially write separate files for consumption by resolvconf. I've only tested on a single interface system so far.

Seems like this sort of thing could be plumbed with https://gitlab.com/craftyguy/networkd-dispatcher in configured.d .

I tried to use a SearX instance again but it kept getting throttled so I had to fall back to something else. Why can't we have a nice, non-AI-inundated, #IPv6 enabled search engine?

Weiß jemand, wie man unter Windows ohne DHCP stabile iid bekommt?

Kann man auch Token setzen?

Oder eben vielleicht doch eui64 erzwingen?

Part of me wants to upgrade the WNDR3800 I'm using for my portable #IPv6 lab to the latest OpenWrt, but part of me is rather skittish about it after the debacle with the Ubiquiti hardware.

@drscriptt again: I'd see this as more error-prone than #DNSSEC and only hindering the transition from #IPv4 to #IPv6 if not bricking proper #DualStack…

@drscriptt Naive question: WHEN does the average #Internet #user ever open up a webpage with an #IP address instead of a #domain or even #FQDN?

• Seriously, the only cases I saw were either some old, non-public - facing server in some B2B/API setting or a test that #httpd / #ngnix / #ssh / … function properly on like a #VPS and that the #DNS hasn't been updated (yet!) to include said host / FQDN in the records, and even then it's bad cuz you'd rather want to use it's FQDN instead because with #IPv4 shortages on one hand and tools like #Portainer on the other, one should not use an #IPaddress as addressing method because #WAF / #Proxies used to "#MUX" / "#NAT" services under one IP address or #IPv6 block may need that distinction by being queried for a specific FQDN...

The Idea if !SSL / #TLD for #IPaddresses makes me feel like Jeff Goldblum!

Same..., different day.

@jima Minnesota and #IPv6 represent: https://openriver.winona.edu/rca/2025/schedule/92/

I wish we could see their code. I see lots of chatter about NAT64 and eBPF but I haven't yet found anything I can actually load.

@leyrer @farbenstau #ipv6 by default, that sounds proper!

@niklas @mattgrayyes worse even if one doesn't setup an account just to watch videos!

Then one cannot disable that shite which solely selects the used language based off vibes, which is really annoying when one has different #GeoIP "localizations" depending on whetger #IPv4, #IPv6 and whether one is on #Mobile or at home or at work!

Really makes me angry af!

Countries, where all mobile networks provide #IPv6 for data use.

de (Telekom, Vodafone, O2, 1&1)
fr (bouygues, free, orange, sfr)
cz (O2, Vodafone, T-Mobile)

us (T-Mobile, Verizon, AT&T, ?) ?

Is there a overview?

Can you confirm that your mobile ISP in your country supports ipv6?

Yes, The Book of PF, 4th Edition Is Coming Soon https://nxdomain.no/~peter/yes_the_book_of_pf_4th_ed_is_coming.html

Does anyone know how to run an #IPv6 #464XLAT #CLAT client inside a #Proxmox LXC container? clatd ( https://github.com/toreanderson/clatd ) doesn't work because tayga is unable to create a tun interface inside the LXC and I have some software to run that, you guessed it, is still stuck on the obsolete protocol + I don't want to create a full VM just for it.

Bouygues-Telecom with #iOS

Using defaults during roaming results in ipv4-only.

https://www.thomas--schaefer.de/apn-ipv4-ipv6.html#bouygues
https://www.thomas--schaefer.de/roaming/Bouygues-Telecom.mobileconfig

Using that profile enables #ipv6 .

Hotspot during roaming works now. IPv4(clat) is broken and IPv6-mostly is not provided. But in generell IPv6 with NAT64 works.

I think the @BoxyBSD project is one of the best ideas for the #opensource community. Providing real and completely free #VPS instances (#VMs) with #IPv6 is really great for testing and learning.

I really love this project and if you are into #FreeBSD or any other #BSD this might be interesting for you. Just as it is also a #free alternative to bigger hostels like #Hetzner #OVH or #Netcup. I really love the philosophy and idea behind it

If you believe that AI is inevitable but #IPv6 is not, well, you're probably not even reading this since we don't live in the same reality.

AWS Site-to-Site VPN now supports IPv6 addresses on outer tunnel IPs
Posted on: Jul 8, 2025

https://aws.amazon.com/about-aws/whats-new/2025/07/aws-site-to-site-vpn-supports-ipv6-addresses-outer-tunnel-ips/

Some back-of-the-napkin math for those worried that we might still exhaust #IPv6 if we're not careful:

We are currently numbering out of 2000:/3, but effectively it's been 2000::/4 so far. The smallest amount of space that can be announced in BGP is a /48.

4 bits off the top and 16 bits off the bottom leaves us with 2^28 individual /48 networks we _could_ issue (obviously we're issuing larger chunks where possible, eg: /32 for many ISPs). This is representable without having to go to engineering notation: 268,435,456.

Last night's bgp.tools dump shows 117,731 active ASNs. We could issue every org with an ASN a starter /48 and still have several orders of magnitude worth of room for growth. And that's even before we get to 3000::/4.

So, don't worry about filling up the pool. Grab what you need (and maybe a bit more) and build the network you've been dreaming of.

I bought a eSIM from Bouygues Telecom for travelers.

The default setting on Android for roaming (IPv4) was wrong. But after changing it to #IPv6 it works. Firewall settings seem a little bit strange (no ping, other ICMP packets are also blocked).

464xlat (clat) works.

My first SIM with 464xlat during roaming.

Ratestunde!

Wie / in welchem Format muss die #IPv6 localhost Adresse in die #gitlab config, damit sie passend ins yaml gerendert werden kann und danach auch von da passend in die weiteren configs gerendert werden kann?

(ganz konkret gehts um den config eintrag `nginx['real_ip_trusted_addresses']`)

Hint: `::1` ist's nicht.

One slightly weird thing I had is that inbound #ipv6 traffic on both SSH and HTTPS was returning a "connection reset by peer" for a while. It seems to be working now, but if some IPv6 folks can check https://cablespaghetti.dev loads properly over v6 for them now, it would put my mind at rest.
