"Swisscom’s mobile services deliver reliable and highly
secure coverage in Switzerland and internationally.
Among the two primary mobile services, voice and data,
Voice over LTE (VoLTE) already utilises IPv6. With the
introduction of a Dual Mode 5G Mobile Core in 2025,
we are laying the foundation to ensure that in 2026,
Swisscom’s entire mobile offerings will be either
IPv6-only or at least IPv6-first."

I made also the windows test - in case option 108 is not provided by the client, iOS provides IPv4

#RUNBSD! But BoxyBSD now also starts to support #Linux! We're starting soon with the Linux support for already present users, offering free boxes:

* #AlmaLinux
* #Alpine
* #Debian
* #Devuan
* #CentOS
* #Fedora
* #Gentoo
* #OpenSuse
* #OpenEuler
* #RockyLinux

Just next to our core OS like #FreeBSD, #OpenBSD, #NetBSD, #MidnightBSD and #DragonflyBSD (and #illumos). This should also make the step easier to compare and test different scenarios where BSD provides a different behavior compared to Linux systems.

Thanks to @gyptazy for the implementation!

I found the handwritten notes from the first #IPv6 talk I attended in June 2010 that would set me on this journey. I'm working on a blog post about it but I am out of practice in long-form writing.

Question for those who know: is it meaningful to attempt to geolocate an #IPv6 address?

This may sound like a dumb question, but with IPv6 am I supposed to ... learn the addresses like I have for IPv4?

With IPv4 I feel as if I have had a reasonable chance of learning some of the important blocks, but with IPv6... I genuinely hesitate to "adopt" because I fear having to learn the new addressing scheme.

If not, how should I ... "think" about IPv6 coming from the perspective of actually knowing IPv4-addresses?

#Networking #IPv6 #IPv4

We are hiring for both a Director of Product Management and a Senior Product Architect for Cloud Networking (eg, within #Linode / #akamai_technologies Cloud). The former is a remote US position while the latter is a remote Czechia/Poland position.

Come help specify and design a modern cloud networking platform (eg, utilizing IPv6-centric design patterns, while also meeting legacy IPv4 needs).

I love working at Akamai which is why I've been at the company for 26 years now. We have lots of great employees, a global culture that values diversity and inclusivity, and no shortage of fun problems to solve.

#FediHire #IPv6

Fun-Fact: Our Mastodon instance "burningboard.net" doesn't just have the IPv6 address 2a01:4f8:1c1c:4d2::1 but is also reachable via 2a01:4f8:1c1c:4d2::fed1
as well as
2a01:4f8:1c1c:4d2:fed1:fed1:fed1:fed1

Might not make much sense, but it's funny :)

Amazon CloudWatch adds IPv6 support
Posted on: Jul 24, 2025

https://aws.amazon.com/about-aws/whats-new/2025/07/amazon-cloudwatch-adds-ipv6-support/

Ahhh, how painful IPv6 still is when it comes to Kubernetes and such…

Just playing around with microk8s and dual-stack networking.

The minute I enabled IPv6, everything broke apart:
- coredns get a different IPv4 breaking service discovery
- documentation implicitly tells you to use ULA, no NAT applied
- switching to GUAs breaks other things I didn’t understand why

Now I got dual-stack in NAT mode going and I’m not sure whether I like it or not.

#IPv6 #Kubernetes

@arichtman Not quite the same level as #GitHub no #IPv6!

Melbourne airport no IPv6, boo

#IPv6

There are still LIRs without #IPv6 . 😕

~1000 LIRs still begging for #IPv4 addresses 🤔

#ripe region

@timcappalli All these router/firewall appliance vendors seem to be allergic to "new" things like #IPv6, Wireguard, ACME (looking at you, WatchGuard)

What I want from #Mozilla: Overhaul their infrastructure so I can reach all[1] of their resources via #IPv6

What we get from Mozilla: AI 😔

[1] It only took them 7 years to get addons.mozilla.org working: https://bugzilla.mozilla.org/show_bug.cgi?id=1354049 . firefox.com now answers on IPv6 but links to download.mozilla.org which does not. Their infra is such a hodge-podge.

Did you know Bastille supports dual-stack networking at create-time for VNET jails?

Speedtest assumes the ISP for your IPV4 connection is the same as for IPV6, this can attribute wrong metrics to a provider.

There's no way I could pull ~ 1100 Mbps over KPN which currently still runs over copper, this speed is actually thanks to Ziggo over good old coaxial cable.

#speedtest #KPN #Ziggo #ipv6

Alt...

Speedtest result for a test from KPN with (masked) IPV4 address, which is a wrong result since the actual test was over another provider over IPV6. The test result show download: 1165 Mbps, Upload: 11 Mbps.

Last weekend.
Slightly different...
