Heavy Networking 663: OpenAI For Networking
Would you give an artificial intelligence responsibility to write your router configurations? You wouldn’t. Not yet. But we’re not as far from that as you might think. On today's Heavy Networking we dig into OpenAI and ChatGPT and what it might mean for networking.

Passpoint can free up tremendous time and energy for IT and network managers so they can focus on more strategic tasks which add value to the organization in the medium and long term.Being the Best at Beginning
The other day I was listening to an excellent episode of The Art of Network Engineering talking about technical marketing engineers (TME). The discussion was excellent and there was one line from Pete Lumbis in the episode that stuck with me. He said that one of the things that makes you good as a TME is being an “expert beginner”. That phrase resonates at lot with me.
Fresh Eyes on the Problem
I talked a bit about this last year when I talked about being a beginner and how exciting that it was to start over with something. As I compared that post to the AONE episode I realized that what Pete was talking about was a shift in mindset that gives you the energy and focus to pick things up quickly.
You may have heard the phrase “familiarity breeds contempt”. It’s a common phrase used to describe how we feel less impressed with things the more we learn about then. Our brains are wired to enjoy new things. We love new experiences, going to new places, or even meeting new people. The excitement and rush that we get from something unfamiliar causes our brain to devour things. It’s only Continue reading
Cyberattacks on Holocaust educational websites increased in 2022
Today we mark the International Holocaust Remembrance Day. We commemorate the victims that were robbed of their possessions, stripped of their rights, deported, starved, dehumanized and murdered by the Nazis and their accomplices. During the Holocaust and in the events that led to it, the Nazis exterminated one third of the European Jewish population. Six million Jews, along with countless other members of minority and disability groups, were murdered because the Nazis believed they were inferior.
Seventy eight years later, after the liberation of the infamous Auschwitz death camp, antisemitism still burns with hatred. According to a study performed by the Campaign Against Antisemitism organization on data provided by the UK Home Office, Jews are 500% more likely to be targeted by hate crime than any other faith group per capita.
Cyberattacks targeting Holocaust educational websites
From Cloudflare’s vantage point we can point to distressing findings as well. In 2021, cyberattacks on Holocaust educational websites doubled year over year. In 2021, one out of every 100 HTTP requests sent to Holocaust educational websites behind Cloudflare was part of an attack. In 2022, the share of those cyber attacks grew again by 49% YoY. Cyberattacks represented 1.6% of all Continue reading
Inside Geo Key Manager v2: re-imagining access control for distributed systems
In December 2022 we announced the closed beta of the new version of Geo Key Manager. Geo Key Manager v2 (GeoV2) is the next step in our journey to provide customers with a secure and flexible way to control the distribution of their private keys by geographic location. Our original system, Geo Key Manager v1, was launched as a research project in 2017, but as customer needs evolved and our scale increased, we realized that we needed to make significant improvements to provide a better user experience.
One of the principal challenges we faced with Geo Key Manager v1 (GeoV1) was the inflexibility of our access control policies. Customers required richer data localization, often spurred by regulatory concerns. Internally, events such as the conflict in Ukraine reinforced the need to be able to quickly restrict access to sensitive key material. Geo Key Manager v1’s underlying cryptography was a combination of identity-based broadcast encryption and identity-based revocation that simulated a subset of the functionality offered by Attribute-Based Encryption (ABE). Replacing this with an established ABE scheme addressed the inflexibility of our access control policies and provided a more secure foundation for our system.
Unlike our previous scheme, which limited future Continue reading
Towards a global framework for cross-border data flows and privacy protection
As our societies and economies rely more and more on digital technologies, there is an increased need to share and transfer data, including personal data, over the Internet. Cross-border data flows have become essential to international trade and global economic development. In fact, the digital transformation of the global economy could never have happened as it did without the open and global architecture of the Internet and the ability for data to transcend national borders. As we described in our blog post yesterday, data localization doesn’t necessarily improve data privacy. Actually, there can be real benefits to data security and - by extension - privacy if we are able to transfer data across borders. So with Data Privacy Day coming up tomorrow, we wanted to take this opportunity to drill down into the current environment for the transfer of personal data from the EU to the US, which is governed by the EU’s privacy regulation (GDPR). Looking to the future, we will make the case for a more stable, global cross-border data transfer framework, which will be critical for an open, more secure and more private Internet.
The privacy challenge to cross-border data flows
In the last decade, we have Continue reading
Built.fm Podcast with David Gee
I had a lovely chat with David Gee on his built.fm podcast sometime in December. David switched jobs in the meantime, and so it took him a bit longer than expected to publish it. Chatting with David is always fun; hope you’ll enjoy our chat as much as I did.
Hedge 163: Netops, Mapping, and Working Hard
It’s one of those episodes where Tom, Eyvonne, and Russ just sit around and talk about the news of the day. We cover three topics in this show. The first is Netops, automation, and where this is all going. The second is on the FCC mapping process and the reality of broadband in the US. The third—perhaps a little controversial—is about IT work habits, innovation, and adding value.
Calico Open Source 2022 highlights
2022 has been a year full of new releases, new events, and new projects for Open Source Calico. Let’s take a look at Project Calico’s 2022 highlights and see if you’ve missed any exciting news.
New version releases

Azure Networking Fundamentals: Internet Access with VM-Specific Public IP
Comment: Here is a part of the introduction section of the Third chapter of my Azure Networking Fundamentals book. I will also publish other chapters' introduction sections soon so you can see if the book is for you. The book is available at Leanpub and Amazon (links on the right pane).
In chapter two, we created a VM vm-Bastion and associated a Public IP address to its attached NIC vm-bastion154. The Public IP addresses associated with VM’s NIC are called Instance Level Public IP (ILPIP). Then we added a security rule to the existing NSG vm-Bastion-nsg, which allows an inbound SSH connection from the external host. Besides, we created VMs vm-front-1 and vm-Back-1 without public IP address association. However, these two VMs have an egress Internet connection because Azure assigns Outbound Access IP (OPIP) addresses for VMs for which we haven’t allocated an ILPIP (vm-Front-1: 20.240.48.199 and vm-Back-1-20.240.41.145). The Azure portal does not list these IP addresses in the Azure portal VM view. Note that neither user-defined nor Azure-allocated Public IP addresses are not configured as NIC addresses. Instead, Azure adds them as a One-to-One entry to the NAT table (chapter 15 introduces a Continue reading
Writing An IETF Draft: Formatting, Authorship, And Submissions
This series started by discussing the history of the IETF and some of the tools you might use to build submissions to the IETF process. This, the second, post, will consider document formatting and two of the (sometimes) more difficult sections of an IETF draft to fill in. Formatting Just using one of the acceptable […]
