IPv6 Buzz 130: Routing With Link-Local Addresses
In this IPv6 Buzz episode, Ed, Scott, and Tom get technical (and maybe a little controversial) with a discussion about using IPv6 link-local addresses instead of globally scoped addresses (e.g., GUA and ULA) along with when and why you might choose to do so.

DLP Exact Data Match beta now available
The most famous data breaches–the ones that keep security practitioners up at night–involved the leak of millions of user records. Companies have lost names, addresses, email addresses, Social Security numbers, passwords, and a wealth of other sensitive information. Protecting this data is the highest priority of most security teams, yet many teams still struggle to actually detect these leaks.
Cloudflare’s Data Loss Prevention suite already includes the ability to identify sensitive data like credit card numbers, but with the volume of data being transferred every day, it can be challenging to understand which of the transactions that include sensitive data are actually problematic. We hear customers tell us, “I don’t care when one of my employees uses a personal credit card to buy something online. Tell me when one of my customers’ credit cards are leaked.”
In response, we looked for a method to distinguish between any credit card and one belonging to a specific customer. We are excited to announce the launch of our newest Data Loss Prevention feature, Exact Data Match. With Exact Data Match (EDM), customers securely tell us what data they want to protect, and then we identify, log, and block the presence or movement Continue reading
AI Workloads Spur Competition in Networking Chips

Overlay Management
I was lucky enough to participate in Tech Field Day 27 a couple weeks months ago. This event brings independent thought leaders together with a number of IT product vendors to share information and opinions. I was not paid to attend, but the organizers did provide travel, room, and meals while I was there. There is no expectation of providing any content, so the fact that I’m mentioning it says something. It was a great event and worth a few hours to check out the videos. Thanks to Gestalt IT for getting me involved.
One of the companies that presented was Men & Mice. They have a product called Micetro (great name!) that manages your DHCP, DNS, and IPAM for you. The product doesn’t provide DHCP, DNS, or IPAM services; it manages it. That is, it configures and monitors those services for you, whether it’s running on your local network, in cloud, remotely, whatever. This is what they call overlay management.
What does that really mean, though? Since overlay management doesn’t provide endpoint services, your endpoints don’t see anything different. Your DHCP servers stays the same. DNS servers stays the same. IPAM stays the same. The only thing that’s Continue reading

How the Cloudflare global network optimizes for system reboots during low-traffic periods
To facilitate the huge scale of Cloudflare’s customer base, we maintain data centers which span more than 300 cities in over 100 countries, including approximately 30 locations in Mainland China.
The Cloudflare global network is built to be continuously updated in a zero downtime manner, but some changes may need a server reboot to safely take effect. To enable this, we have mechanisms for the whole fleet to automatically reboot with changes gated on a unique identifier for the reboot cycle. Each data center has a maintenance window, which is a time period - usually a couple of hours - during which reboots are permitted.
We take our customer experience very seriously, and hence we have several mechanisms to ensure that disruption to customer traffic does not occur. One example is Unimog, our in-house load balancer that spreads load across the servers in a data center, ensuring that there is no disruption when a server is taken out for routine maintenance.
The SRE team decided to further reduce risk by only allowing reboots in a data center when the customer traffic is at the lowest. We also needed to automate the existing manual process for determining the window Continue reading
OpenShift and Ansible: Bridging the Automation Gap for 5G and Beyond Networks – Part 1
This blog post is co-authored with Ian Miller.
5G and beyond mobile networks are requesting automation capabilities to rapidly scale up their service rollout. To that end, Kubernetes and cloud-native infrastructures unlock a great deal of flexibility through declarative configuration.
However, there is a large number of important non-declarative components (e.g. legacy OSS/BSS systems, bare metal servers, network infrastructure, etc.) that will still require imperative configuration for the foreseeable future.
In this series of two articles, we bring together powerful tools and concepts for effectively managing declarative configurations using Red Hat OpenShift, Red Hat Advanced Cluster Management for Kubernetes, and Red Hat Ansible Automation Platform for integrating any non-declarative system into closed-loop automation workflows.
Declarative vs Imperative, a Zero-Sum Game for 5G?
Short answer: definitely not.
Kubernetes and Red Hat OpenShift are built around a declarative model in which configuration Custom Resources (CRs) capture the desired end state and the cluster works to reconcile to it. This model fits in seamlessly with tools like GitOps and the different engines (i.e. clusters, applications, observability, and governance) provided by Red Hat Advanced Cluster Management for Kubernetes.
Both tools are thoroughly leveraged by the Red Hat Zero Continue reading
