Some time ago I asked on Mastodon if someone would be interested in a series of videos about IPv6. Some people are, so I’ll give it a try. Each video will be accompanied by a blog post. This blog post and other materials will be available on gitlab. Starting in January 2025, videos will come out every Tuesday evening (CET) and I’ll try to keep them between 10 and 20 minutes.

Last week I talked about ContainerLab at our admin meetup in Berlin. Containerlab provides a CLI for orchestrating and managing container-based networking labs. It starts the containers, builds a virtual wiring between them to create lab topologies of users choice and manages labs lifecycle. As allways the presentation was streamed and recorded. Talk was in German, slides are in English: Recording Slides

The basic Idea: What if we put together an “advent of IPv6” just like – https://adventofcode.com/ or https://tryhackme.com/r/christmas Gitlab repo including my slides from RIPE89 https://gitlab.com/jenslink/advent-of-ipv6 There is also a mailing list: https://list.sys4.de/postorius/lists/ipv6-advent-orga.lists.quux.de/

You want to make a presentation, write a blog post or document your brand-new software. What do you use as domain-names, IP addresses and AS numbers? If you are documenting your systems or a setup you build for a customer the question is easy to answer: It’s best to use the actual data. But if you are writing a more generic documentation there are some reserved domain names, IP prefixes and AS numbers.

Welcome to my new blog. Yes, a new blog at the end of 2024. Since the last post in my old blog in February 2019 I moved to the other side of Berlin, worked on several interesting projects and accumulated quite a lot of ideas of things I should document or learn about and then document. What to expect? So as I’m an old nerd, who is using Linux since he first got it an 35 3.
