In order for one device to talk to other devices on the Internet using the aptly named Internet Protocol (IP), it must first be assigned a unique numerical address. What this address looks like depends on the version of IP being used: IPv4 or IPv6.
IPv4 was first deployed in 1983. It’s the IP version that gave birth to the modern Internet and still remains dominant today. IPv6 can be traced back to as early as 1998, but only in the last decade did it start to gain significant traction — rising from less than 1% to somewhere between 30 and 40%, depending on who’s reporting and what and how they’re measuring.
With the growth in connected devices far exceeding the number of IPv4 addresses available, and its costs rising, the much larger address space provided by IPv6 should have made it the dominant protocol by now. However, as we’ll see, this is not the case.
Cloudflare has been a strong advocate of IPv6 for many years and, through Cloudflare Radar, we’ve been closely following IPv6 adoption across the Internet. At three years old, Radar is still a relatively recent platform. To go further back in time, we Continue reading
netlab: Version-Specific Topology Files
TL&DR: If you’re using netlab to build labs for your personal use, you can skip this one, but if you plan to use it to create training labs (like my BGP labs project), you might want to keep reading.
Like any complex enough tool, netlab eventually had to deal with inconsistent version-specific functionality and configuration syntax (OK, topology attributes). I stumbled upon this challenge when I wanted to make labs that use two types of configurable devices.

Why Secure SD-WAN is a Pillar of Enterprise Cybersecurity
While the networking industry chatter is centered on hot topics like ZTNA and SASE, it's easy to forget to check in on existing solutions like SD-WAN.Fighting Back Against Fileless Malware
Fileless malware attacks are extremely hard to detect and the time it takes for them to be discovered is growing. The best approach to dealing with it is preventing the malware from infecting a network by adopting a zero-trust approach.D2C224: Security KubeConversations Part 1 – Protecting Your Kubernetes Infrastructure
Our KubeConversations series continues with a two-part episode on securing Kubernetes and cloud-native infrastructure. I attended KubeCon 2023 in Chicago and had the opportunity to speak with vendors and open-source maintainers about the work they're doing to help protect your Kubernetes environments. I talk about a Kubernetes Bill of Materials, protecting K8s from ransomware, protecting APIs and Web front-ends from attacks, and the state of cloud-native security.
