Explore Configurations of Unfamiliar Devices with netlab

Apart from IP multicast and QoS, netlab can configure commonly used networking technologies across dozens of devices from most networking vendors. Why don’t you use all that embedded knowledge (supported by hundreds of integration tests) to help you configure unfamiliar devices?

You don’t have to install VM or container managers (Vagrant/containerlab), or beg vendors to give you access to device VMs/containers, to get working device configurations. All you need is a Python package that works on Windows1, macOS, or Linux.

It’s as simple as this:

NANOG 96 was held in February 2026 at San Francisco. Here are my impressions on some of the presentations that were made at that meeting.

Aleix Segura Vendrell: Pria Spanyol yang Tahan Napas 24 Menit 3 Detik di Bawah Air

Aleix Segura Vendrell adalah nama yang sudah terukir dalam sejarah freediving dunia. Pria Spanyol ini berhasil mencapai prestasi luar biasa dalam discipline static apnea dengan memecahkan rekor dunia Guinness. Pada kesempatan ini kita akan membahas siapa dia, bagaimana caranya mencapai pencapaian fenomenal ini, dan apa artinya bagi dunia olahraga serta batas kemampuan manusia.


Siapa Itu Aleix Segura Vendrell?

Aleix Segura Vendrell lahir di Barcelona, Spanyol. Ia bukan sekadar atlet biasa. Sejak awal, Aleix menunjukkan ketertarikan kuat pada dunia bawah air. Melalui spearfishing, ia mengembangkan kemampuan apnea atau menahan napas dalam air dan akhirnya masuk ke dunia kompetitif freediving sejak 2011.

Berbeda dengan kebanyakan atlet, Aleix memiliki karier profesional di luar olahraga. Ia bekerja sebagai arsitek di Barcelona, namun tetap konsisten menjalankan latihan ekstrem untuk mencapai batas sistem pernapasan manusia.

Lebih jauh lagi, Aleix berhasil meraih gelar juara dunia static apnea di beberapa federasi besar. Hal ini menegaskan posisinya sebagai salah satu atlet freediving terbaik di dunia.

Metabolisme Bakteri vs Virus: Perbedaan, Dampak, dan Cara Hidup

Pengantar Perbedaan Bakteri dan Virus

Bakteri dan virus sering disamakan karena sama-sama mikroskopis. Namun, keduanya memiliki perbedaan metabolisme yang sangat mendasar. Oleh karena itu, pemahaman ini menjadi penting dalam biologi, kedokteran, dan kesehatan masyarakat. Selain itu, perbedaan metabolisme juga memengaruhi cara pengobatan dan pencegahan penyakit. Dengan memahami konsep ini, kita dapat menentukan strategi penanganan infeksi secara tepat. Selanjutnya, artikel ini membahas perbedaan tersebut secara rinci, sistematis, dan mudah dipahami.

Pengertian Metabolisme dalam Biologi

Metabolisme adalah seluruh reaksi kimia yang terjadi dalam makhluk hidup. Proses ini mendukung pertumbuhan, reproduksi, dan kelangsungan hidup. Selain itu, metabolisme mencakup anabolisme dan katabolisme. Anabolisme membangun molekul kompleks. Sebaliknya, katabolisme memecah molekul untuk menghasilkan energi. Dengan demikian, metabolisme menjadi ciri utama kehidupan sejati. Oleh karena itu, perbedaan metabolisme menegaskan perbedaan tingkat kehidupan bakteri dan virus.

Metabolisme pada Bakteri

Bakteri merupakan organisme prokariotik yang hidup mandiri. Oleh sebab itu, bakteri memiliki sistem metabolisme lengkap. Bakteri mampu menghasilkan energi sendiri. Selain itu, bakteri dapat melakukan respirasi aerob atau anaerob. Continue reading

The Current AI Networking Wave Will Be A Tsunami Of Money By 2027

$230.70. That’s it.

If you take the $34.6 billion that Arista Networks has made in product revenue since it was founded way back in 2004 by Andy Bechtolsheim, David Cheriton, and Kenneth Duda and divide it by the 150 million cumulative ports that it has shipped (with the product ramp really starting in 2010 after the company dropped out of stealth mode in 2009) This is a remarkable number give the fact that Arista has tended to ship very expensive ports that often cost $1,000 or more without services on top of them.

TNO055: Testing as a Service for Telco Network Services

Scott talks with Mark Gebert from Verizon about something that sits at the heart of every reliable enterprise network: testing. Automation is moving fast in the telco world, but automation without testing is just an accident waiting to happen. They unpack what makes enterprise service provisioning so complex—multi-vendor networks, optical and IP gear, security functions,... Read more »

Shedding old code with ecdysis: graceful restarts for Rust services at Cloudflare

ecdysis | ˈekdəsəs |

noun

the process of shedding the old skin (in reptiles) or casting off the outer cuticle (in insects and other arthropods).

How do you upgrade a network service, handling millions of requests per second around the globe, without disrupting even a single connection?

One of our solutions at Cloudflare to this massive challenge has long been ecdysis, a Rust library that implements graceful process restarts where no live connections are dropped, and no new connections are refused. 

Last month, we open-sourced ecdysis, so now anyone can use it. After five years of production use at Cloudflare, ecdysis has proven itself by enabling zero-downtime upgrades across our critical Rust infrastructure, saving millions of requests with every restart across Cloudflare’s global network.

It’s hard to overstate the importance of getting these upgrades right, especially at the scale of Cloudflare’s network. Many of our services perform critical tasks such as traffic routing, TLS lifecycle management, or firewall rules enforcement, and must operate continuously. If one of these services goes down, even for an instant, the cascading impact can be catastrophic. Dropped connections and failed requests quickly lead to degraded customer performance and business impact.

When communication networks break down, people cannot report their condition, responders lose situational awareness, and entire communities risk slipping beyond the reach of coordinated assistance. Network failure does not merely accompany disaster — it reshapes the human consequences.

Nuclear is the Most Reliable Path to Affordable Electricity  


Amid this “worldwide” economic backdrop, nuclear energy presents an affordable alternative to unreliable electricity sources like wind and solar. Economically, it makes no sense to abandon working production methods until new ones can replace the existing and future demand. World citizens are facing this reality in higher electricity prices.

There have been a number of services that allow a lookup of an IP address or Autonomous System Number (ASN) and return information about that IP number resource. The Regional Internet Registries (RIRs) each operate a database that records (among other data items) the number resource and the details of the entity that is described in the relevant number registration record.

Lab: Build an SR-MPLS Network with IS-IS

Want to spend an hour or two configuring some cool stuff this weekend? How about getting SR-MPLS to work with IS-IS and building a BGP-free core with it?

If you already set up your own netlab environment, you probably know what to do (or you can get the details here). Alternatively, you can click here to start the lab in your browser using GitHub Codespaces. After starting the lab environment, change the directory to advanced/10-sr and execute netlab up.

The Memory Crunch Pinches Cisco’s Profits

It has taken many years for the AI boom to reach the general ledgers and balance sheets of the world’s largest original equipment manufacturers, and one might say that it has taken particularly long for Cisco Systems, the dominant supplier of switching and routing in the enterprise and traditional telco/service provider spaces as well as a respectable systems supplier with over 90,000 customers using its UCS converged server-switch platforms.
