OMG, i thought things were supposed to get simpler as newer versions of software came out.

On the "Legacy" ISC #DHCP settings in #OPNSense, you could just type an IP address into the NTP text box.

In the "improved" version, which uses Kea DHCP instead, it will only accept "hex".

I assume this is just the #IPv6 address with no ":"s and loads of "0000"s (in my case), but some guidance would be helpful.... or just a fucking text box specifically for a IP address like the "legacy" version <sigh>.

Alt...

"Legacy" page, showing a sensible text box that accepts a simple IPv6 IP address

Alt...

The "newer" Kea DHCPv6 options, where you've got to somehow put the IPv6 address in hex

@tschaefer But it adheres to the RFCs and generates an #IPv6 address for the CLAT.
But I haven't found a way to see this on the host. I see it on the segment in the Neighbour table fine.

Want to help testing #CLAT on Linux and run #networkmanager?

#IPv6

Dear #Lazyweb,

Has anyone in the UK managed to get a working #IPv6 configuration with #PlusNet's FTTP broadband service? If so, please could you share a HOWTO?

@pojntfx you at least have #IPv6!

• I'm stuck behind #IPv4only connectivity with #CGNAT on #mobile that also violates RFC6598 by using RFC1918 [10.0.0.0/8] address space, bricking #VPN|s!
  • So the only way to get shit done is to Reverse-#SSH things and VPN stuff.

OFC @BNetzA doesn't give a damn…

RE: https://raphus.social/@MaddieM4/116647470097885752

I absent-mindedly clicked on the torrent link, which downloaded fine on my NAT64 system. I scp'd it over to my torrent box, which is #IPv6 only, and was somehow able to download the whole thing. But now I'm seeding to nowhere because the trackers are all legacy-only as well.

I realize Kiwix's thing is offline mirrors, but we still need to get IPv6 to the still-online parts. Anybody feel like reaching out to them to see what their blockers are?

Update on this. I got my video software set back up, and I'm currently downloading all 115GB of the February 2026 dump of Wikipedia. Why then? Because it's the most recent dump on Kiwix to actually include images (I could have gone more recent without them).

Anyways I probably won't have that video out today because it's predicted to take 20 hours to download by torrent. I would absolutely welcome some other folk sharing the load and improving torrent resiliency.

Can somebody who knows Terraform help me out here?

#IPv6

Tried to go to bed so of course my brain decides to come up with a new idea rather than fall asleep.

A website that generates a new random-ish image or 3D world or something unique based on a 128-bit seed value. Think UUID (isn't this how Minecraft works?), but instead it would use your #IPv6 client address. Hopefully the novelty would be sufficient to generate some buzz.

If you don't have IPv6, you simply could not reach the site. There would be a brief note in the About page noting that there have been reports the site is not reachable from some parts of the Internet and you should ask your ISP for assistance if this is the case. This way someone who saw it on, let's say, their mobile phone would wonder why it wasn't working on their home connection.

It would not mention IPv6 at all. Make the ISPs actually have to start troubleshooting this stuff from a genuinely confused consumer rather than blindly telling techies "We have no plans to deploy that."

A bonus could be to use a 256-bit seed, combining the server and client addresses, so there could be a bunch of these sites out there. Maybe turn it into a digital scavenger hunt. I've always thought there should be a sequel to SixSpotting :)

The artistry part is probably beyond my ken. Any digital artists out there picking up what I'm throwing down?

I know "AI" is a polarizing topic around here, but I wanted to share a small side-project I've been tinkering with to scratch a personal itch: MastoSum.

It’s a lightweight web app that listens to public streams, filters for the hashtags I actually care about, and uses an LLM to generate a daily digest of the last 24 hours. Basically, a personalized news feed to help cut through the noise.

It works reasonably well for what I need. Here’s an example of today's run: https://mastosum.linuxserver.pro/s/6q1ZdTOuHBfKyQ3aVU3dOw

It's IPv6-only. Not reachable via IPv4.

One additional test with roaming.
No chance to get #ipv6 for data.

(VoLTE has IPv6)

That's strange.
Within UK ee provides IPv6only, outside of UK IPv4only.

@autobrain Aproveitando o retorno triunfal do #BRLinux , notei que este e os teus demais sites na #DreamHost não estão acessíveis na Internet em #IPv6 . Consegue corrigir este acesso, assim que tiver a possibilidade? ;)

A #DreamHost fornece a documentação de como faze-lo aqui: https://help.dreamhost.com/hc/en-us/articles/216510458-IPv6

@altf4 #Ecosia has #IPv6 and you help them planting trees ;)

Dafuk?

So, DuckDuckGo sounded to me like an alternative to google...

Hosted on Microsoft Azure with no #ipv6 ... Ok. Anything else?

Just a reminder: there is a Experimental IPv6-only network

You can check your (web)sites.

#ripe92 #ipv6only #ipv6

Roughly 17 years (-ish) after taking the one/only test available back then, I've returned and taken the "new" IPv6 tests and am now an IPv6 Sage. *flex* ask me about my glue records, they work out.

https://ipv6.he.net/

#dns #ipv6 #networking #nerd #::1

#UK is still broken

with local esim:

#ee IPv6 ✅
#o2 IPv6 ❌
#three ipv6 ❌
#vodafone (not tested)

At least, roaming of foreign sims works with #IPv6 in all cases.
Also VoLTE/IPsec runs via IPv6.
But data...only work with ee.

*knock on wood* My DNS oddities seem to have diminished since I made a config change.

I forward to Quad9 via DoT so my ISP cannot see / interfere with what I'm looking up. I had been using the recommended resolvers and was having intermittent SERVFAILs as well as some problems getting #IPv6 mirrors.

I switched to the Secured w/ ECS resolvers and haven't had any problems since. My threat model doesn't care about the upstream DNS server knowing where I'm originating from since more often than not the target is going to get an incoming connection from me moments after. Bonus that the upstream will always get an IPv6 ECS subnet from me. Maybe a subtle hint to some places that haven't turned it on yet to go ahead and do that?

I suppose it's possible there was some other issue in play that might crop back up on these resolvers, but for now I'll take the win.

Got tired of Asterisk on this old Debian 11 system starting up on boot so fast that it doesn't have an #IPv6 address to bind to, because apparently (in very Inigo Montoya voice) "network-online.target" doesn't mean what you think it means.

So I dropped an ExecStartPre= in a service override that calls this little gem of a shell script:

#!/bin/bash

# Argument: name of interface
# If interface does not exist, script will continue anyway

if [ "$1" == "" ]
then
echo "Specify interface"
exit
fi

ADDR=null

while [ "${ADDR}" == "null" ]
do
sleep 1s
ADDR=$(ip -j -6 addr show dev ${1} scope global | jq -r '.[0].addr_info | .[0].local')
done

Some statements won't be true anymore within the next three weeks. 🤗

1&1 (de)

roaming works with #IPv6 in UK with EE.

MTU is 1500

Dualstack and IPv6only (with NAT64, but without DNS64) is supported. (same as home)

o2 (de):

roaming works with #ipv6 in UK with o2 (uk)

MTU is 1500

Dualstack is provided at home and during roaming.
#IPv6only (really only, no NAT64, no DNS64) is also working at home as well during roaming in UK.

Vodafone (de):

roaming works with #IPv6 in UK with Vodafone (uk)
MTU (1464) is lower than at home (1500)

Deutsche Telekom:
#roaming works with #ipv6 in #uk with ee, o2 and vodafone
MTU is lower (1440) than at home(1500).

(The #IPv6only mode (standard at home) is still not supported)

@tschaefer @JulianOliver: My #IPv6 /48 range at home is native: https://www.init7.net/en/support/faq/Statischer-IPv6-Range/

I could also get a static IPv4 address for some extra money, but it's not worth it anymore — static IPv6 suffices completely.

#Init7 #Fiber7

@JulianOliver: IPv4 or IPv6? (I have a dynamic IPv4 address and a static #IPv6 /48 at home. Who needs IPv4 nowadays, anyway? 🤓)

@BalooUriza Agreed. Any new protocol proposal should include how they intend to speed run the last 30 years of getting #IPv6 into every router and endpoint.

I got a better idea than #IPv8: finish adopting #IPv6 already. ESPECIALLY since IPv8 is just carrier grade NAT on IPv4 stacked in a trenchcoat.
