Bold Statements
This is meant to be the first part of a 3-part series discussing the space & types of IP addresses, with a particular focus on what has changed between IPv4 and IPv6. In this first post I’ll take the audience through a historical tour of some developments within the IPv4 address space.

Continue readingIn some organizations we work with a certain state of IPv6 deployment has been reached in the interim which includes, among others, the following aspects:
It might then happen that networking people (who often are the initial motivators for deploying IPv6) in such organizations are stating, when asked about IPv6: “it’s [mostly] done”.
Point is that, alas, this does not necessarily mean that a single service or application is *actually using* IPv6, so while the above certainly constitutes an achievement it might not even be halfway through.

Continue readingIn this post I’ll cover some properties of the Windows Server 2019 IPv6 stack. It is an update of a similar post I wrote on the IPv6 properties of Server 2016 a while ago. Continue reading “IPv6 Properties of Windows Server 2019 / Windows 10 (1809)”
Continue readingThis week Chris and I participated in the RIPE 78 meeting in Reykjavík. Being part of the group was fun as always and we had quite some interesting conversations with peers from (not only) the IPv6 community.
Big thanks to the RIPE NCC team for the smooth organization and for taking care of us!
In this post I’ll provide some notes on talks I found particularly interesting, plus links to our own contributions.

Continue readingChris and I will give a tutorial on the above topic at next week’s RIPE Meeting in Reykjavík. In this post (actually this will probably become a small series of posts) I’ll try to summarize some thoughts on IPv6 security in enterprise environments in 2019.

Veronika McKillop, Network Architect, Cloud and Connectivity Engineering (CCE)
The speaker, Veronika McKillop, working at Microsofts network infrastructure services, has given a talk about the process of switching a company network from IPv4 to IPv6-only. Continue reading “#TR19 Next Generation Internet (NGI) Summaries”
Continue readingWe’re regularly asked to review IPv6 address plans from different organizations and I’d like to share some reflections from such a process currently happening. I’ve discussed a few aspects of IPv6 address planning before; those readers interested please see this post which contains some references.

Continue readingStarting a post, in 2019, with a mention of sth being “IPv4-only” somewhat hurts ;-), but here we go. Recently Manel Rodero from Barcelona asked me the following question on Twitter:

Continue readingSome years ago Christopher wrote two posts (2016, 2015) about the IPv6-related characteristics of the WiFi network at Cisco Live Europe. To somewhat continue this tradition and for mere technical interest I had a look at some properties of this year’s setting.

Continue readingAt first a very happy new year to everybody!
While thinking about the agenda of the upcoming Troopers NGI IPv6 Track I realized that quite a lot of IPv6-related topics have been covered in the last years by various IPv6 practitioners (like my colleague Christopher Werny) or researchers (like my friend Antonios Atlasis). In a kind of shameless self plug I then decided to put together of list of IPv6 talks I myself gave at several occasions and of publications I (co-) authored. Please find this list below (sorted by years); you can click on the titles to access the respective documents/sources.
I hope some of this can be of help for one or the other among you in the course of your own IPv6 efforts.
Cheers,
Enno
