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.
In some organizations we work with a certain state of IPv6 deployment has been reached in the interim which includes, among others, the following aspects:
the network infrastructure is IPv6-enabled (incl. interface addressing, routing [protocols] and the like).
parts of supporting services (security functions, monitoring, system management) include IPv6 in a proper way.
3rd party providers have been contractually obliged to deliver their services in an “IPv6-enabled” mode (as opposed to only being “IPv6-capable” which was the standard requirement in many RFIs during earlier years).
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.
This 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.
Chris 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.
We’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.
Some 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.
