Does Odido (the old T-Mobile Netherlands) which took over Tweak Internet (they supported IPv6) already support IPv6?

Posted by jpluimers on 2026/01/12

I am writing this early 2025, shortly after Odido introduced “Klik & Klaar” for EUR 25/month: yet another of their internet products, this time over 5G, and yet again: no IPv6 support, just like their DSL and fiber products.

This post is a reminder to check if by now Odido has started supporting IPv6.

I know that at the time of writing, of the large Dutch mobile providers, only KPN supported IPv6, but both Vodafone and Odido didn’t. However, for Vodafone it is not a technical limitation: their bean counters need an upgrade to their billing system. The Odido back-haul technically isn’t ready for IPv6 at all.

Regrettably, The Netherlands has been behind on IPv6 adoption, which is a shame for a knowledge worker country. UK, Belgium, Germany, France, Greece, Hungary and even Russia are doing far better on IPv6 adoption:

Hopefully that has changed by now.

Edit 20261214: no, that has not changed, see a reaction at [WaybackFailed/ArchiveFailed] Odido verhoogt prijs van Klik&Klaar met 1 euro naar 26 euro per maand – Tweakers (which regrettably can neither be archived in the Wayback Machine nor Archive.is):

En Odido heeft ook nog eens geen IPv6. Anno 2026 loop je dan echt enorm achter.

Translated:

And Odido still does not support IPv6. Anno 2026, they are far behind.

Is this the ultimate XKCD “Dependency” derivative?

Posted by jpluimers on 2025/11/29

xkcd modern digital infrastructure torn down by a satisfied looking cat

Besides the August 2025 XKCD infrastructure dependency inspired cartoon on the right, the more recent and great [Wayback/Archive] XCKD: Dependency derivative below is a monumental piece as it combines the recent:

  • fiber outage of the Internet Archive
  • DoS of Cloudflare by itself
  • AWS us-east-1 dependencies outage
  • Crowdstrike DoS of Windows machines
  • framework-du-jour mentality in the JavaScript world
  • many more¹

Some HTTP redirect checking sites compared

Posted by jpluimers on 2025/04/02

 

Every now and then I want to check how a URL redirect, for instance when checking out why a domain failed loading in browsers a while ago because of certificate problems:

The thing was that back then, the site officially did not have a security certificate, but somehow the provider had installed a self-signed one. Most web-browsers then auto-redirect from http to https. Luckily the archival sites can archive without redirecting:

When querying [Wayback/Archive] redirect check – Google Search, you get quite some results. These are the ones I use most in descending order of preference and why they are at that position:

Old xs4all stuff

Posted by jpluimers on 2024/11/29

In the past xs4all.nl had a shell server. In the shell you had a WWW directory which was the route of your personal web-site.

For instance, I had a file there in ~jp/WWW/route/route.html which was served at:

Almost 25 years after KPN bought xs4all, it switched off the shell servers and these links, so I was glad with this warning [Wayback/Archive] Koen de Jonge on Twitter: “Morgen stopt #kpn4all met het aanbieden van shellaccess. Wij willen dat met #Protagio ook gaan aanbieden. Wil je ook #shellacces houden, kijk dan snel op: … #eerlijkecloud”

Many links about free modem/router choice and their configurations for the Dutch KPN internet/VoIP provider

Posted by jpluimers on 2024/02/19

I wrote this post because the xs4all->KPN transition was messy, especially on the VoIP side.

Emails and letters were incomplete lacking some essential information for manual configuration; 2nd line help desk did not return calls; pointers to where to find correct information were lacking.

This kind of is a catch all post with most of the links I found without much of their content so I can refer to them later when writing a more detailed post on how I did get VoIP to work.

So: for my link archive, almost all posts in Dutch.

Found posts

Note the Ziggo Wifispots certificate will often not install on Android the default way

Posted by jpluimers on 2024/01/26

A long time ago, I wrote about Wifispots instellen | Klantenservice | Ziggo « The Wiert Corner – irregular stream of stuff.

For that, you need a Ziggo VPN certificate, which you can download from [Wayback] www.ziggo.nl/content/dam/www.ziggo.nl/tools/WifiSpots certificaten/WifiSpots certificaat Android en Windows Ziggo.crt .

On many Android phones, that does not install the default way any more as back then.

The reason is that it is a CA root certificate (in this case identifying Ziggo as certificate authority) thereby allowing them to issue any certificate. This can be a serious risk, so you have to be really sure to trust them before installing the certificate.
