The believers in the There Be Four Layers religion think everything below IP is just a blob of stuff dealing with physical things:
People steeped in a slightly more nuanced view of the world in which IP is not the centerpiece of the universe might tell you that the blob of stuff we need is two things:
The University of Stuttgart’s High Performance Computing Center (HLRS) in Germany tapped Hewlett Packard Enterprise back in December 2023 to build a prototype hybrid CPU-GPU supercomputer nicknamed “Hunter” to pave the way towards an exascale-class machine it is budgeting to have installed in 2027 called “Herder.” …

If you follow my blogs, you might know that I recently switched to Proxmox from VMware Workstation Pro for my home lab. I’ve already migrated most of my VMs, including Cisco CML, to Proxmox, and the last piece left was EVE-NG. In this blog post, we’ll go through the steps to install EVE-NG in Proxmox. Let’s get started!

EVE-NG doesn’t have official documentation for Proxmox, but it works perfectly fine, and I haven’t faced any issues so far. For this example, I’m using
Most of the VM’s settings can be left at their default values, but there are a couple of changes I had to make. Before diving in, let's have a quick look at Nested Virtualization.

Welcome to the 20th edition of the Cloudflare DDoS Threat Report, marking five years since our first report in 2020.
Published quarterly, this report offers a comprehensive analysis of the evolving threat landscape of Distributed Denial of Service (DDoS) attacks based on data from the Cloudflare network. In this edition, we focus on the fourth quarter of 2024 and look back at the year as a whole.
When we published our first report, Cloudflare’s global network capacity was 35 Terabits per second (Tbps). Since then, our network’s capacity has grown by 817% to 321 Tbps. We also significantly expanded our global presence by 65% from 200 cities in the beginning of 2020 to 330 cities by the end of 2024.
Using this massive network, we now serve and protect nearly 20% of all websites and close to 18,000 unique Cloudflare customer IP networks. This extensive infrastructure and customer base uniquely positions us to provide key insights and trends that benefit the wider Internet community.
In 2024, Cloudflare’s autonomous DDoS defense systems blocked around 21.3 million DDoS attacks, representing a 53% increase compared to 2023. On average, in 2024, Cloudflare blocked 4,870 Continue reading
The United States ban on TikTok went into effect on January 19, 2025, and although service began to be restored after just 14 hours, it was only close to the inauguration of Donald Trump as the 47th President of the United States that associated DNS traffic started to recover to closer to previous levels. In this post, we analyze the events of January 19 and 20, and what they meant for TikTok-related DNS traffic, but also other competitors (including their growth outside the US).
For context, we wrote an initial blog post about the TikTok ban on Sunday, January 19, 2025. The ban was part of the "Protecting Americans from Foreign Adversary Controlled Applications Act," proposed in Congress, which ordered ByteDance to divest due to alleged security concerns. The bill was signed into law by Congress and President Biden in April 2024, and was upheld by the Supreme Court on January 17, 2025.
Aggregated data from our 1.1.1.1 DNS resolver shows — as we’ve posted on social media — that the TikTok shutdown in the US began to impact DNS traffic to TikTok-related domains on January 19, just after 03:30 UTC (22:30 ET on January Continue reading
Whenever I was explaining how one could build EBGP-only data center fabrics, someone would inevitably ask, “But could you do that with IBGP?”
TL&DR: Of course, but that does not mean you should.
Anyway, leaving behind the land of sane designs, let’s trot down the rabbit trail of IBGP-only networks.
One of the goals we’re always trying to achieve when developing netlab features is to make the lab topologies as concise as possible1. Among other things, netlab supports numerous ways of describing links between lab devices, allowing you to be as succinct as possible.
A bit of a background first:
The United States ban on TikTok went into effect on January 19, 2025, and our data showed a clear impact starting after 03:30 UTC (10:30 PM ET on January 18, 2025). The ban was part of the "Protecting Americans from Foreign Adversary Controlled Applications Act," proposed in Congress, which ordered ByteDance to divest due to alleged security concerns. The bill was signed into law by Congress and President Biden in April 2024, and was upheld by the Supreme Court.
Aggregated data from our 1.1.1.1 DNS resolver shows — as we’ve posted on X — that the TikTok shutdown in the US began to impact DNS traffic to TikTok-related domains on January 19, just after 03:30 UTC (22:30 ET on January 18). This includes DNS traffic not only for TikTok, but also for other ByteDance-owned platforms, such as the CapCut video editor. Traffic dropped by as much as 85% compared to the previous week and showed signs of further decline in the following hours.
Around that time, a message indicating the TikTok ban began appearing for US users.
Analyzing data from autonomous systems or networks, traffic from TikTok owner ByteDance’s network (AS396986) in the US Continue reading
Hello my friend,
This blog post is probably the first one, where we start doing more practical rather than foundational things in Python and Go (Golang). Up till now we were going through all possible data types as well as small steps how to deal with files. Today we’ll bring that all together and boost it with practical scenario of parsing data following the most popular data serialization techniques these days
For quite a while I’m trying to hire a good network automation engineer, who shall be capable to write applications in Python, which shall manage networking. The pay is good, so my understanding would be that the candidates’ level shall be good as well. My understanding is sadly far from reality as general skills in software development is poor. I was thinking multiple times, if people who passed my trainings would apply, they could have smashed it (provided they practice). Which means there are a lot of jobs out there, requiring good level of automation and software development skills. But they stay unfulfilled because there are no good candidates. It could be yours.
Boost yourself up!
We offer the following training programs Continue reading
I have a bit of a problem with this setup serving phpIPAM via Nginx reverse proxy, so I said to share the solution which works for me here maybe will help somebody out there. I installed phpIPAM as Docker container following the instructions here: https://github.com/phpipam-docker/phpipam-docker. Using it via plain http was working OK, but I […]

In my previous InfraHub introductory post, we covered installation and the basics of InfraHub. In this second post, let’s explore the ‘Schema Library’ provided by OpsMill, the team behind InfraHub. As mentioned in the previous post, InfraHub doesn’t include any user-defined schemas out of the box, so we need to create our own. However, the Schema Library repository offers a collection of schemas that we can easily import into InfraHub. In this post, we’ll take a closer look at the Schema Library and how to use it.
If you are new to Infrahub and want to learn the basics of what it is and how to install it, feel free to check out my introductory post below.

The way I think about schema is that it is a blueprint that defines the structure of your data. It specifies the nodes (like devices and interfaces), their attributes, and the relationships between them. This allows you to customize how you Continue reading
One of the various attack surfaces in encryption is insuring the certificates used to share the initial set of private keys are not somehow replaced by an attacker. In systems where a single server or source is used to get the initial certificates, however, it is fairly easy for an attacker to hijack the certificate distribution process.
Henry Birge-Lee joins us on this episode of the Hedge to talk about extensions to existing certificate systems where a certificate is pulled from more than one source. You can find his article here.
