IPv6 Buzz 046: Managing Networks With IPv6 And NAT64
In this week's IPv6 Buzz episode, we talk to Cody Christman about managing networks with IPv6 using the critical transition/translation technology NAT64. We cover why overlapping IPv4 addresses are a big driver for using NAT64, the technical debt of IPv4 NAT, how IPv6 re-simplifies networking, and more.
The post IPv6 Buzz 046: Managing Networks With IPv6 And NAT64 appeared first on Packet Pushers.

The History of the URL
This issue was occuring now because the ARPANET was on the verge of switching from its original NCP protocol, to the TCP/IP protocol which powers what we now call the Internet. With that switch suddenly there would be a multitude of interconnected networks (an ‘Inter... net’) requiring a more ‘hierarchical’ domain system where ARPANET could resolve its own domains while the other networks resolved theirs.
Other networks at the time had great names like “COMSAT”, “CHAOSNET”, “UCLNET” and “INTELPOSTNET” and were maintained by groups of universities and companies all around the US who wanted to be able to communicate, and could afford to lease 56k lines from the phone company and buy the requisite PDP-11s to handle routing.
In the original ARPANET design, a central Network Information Center Continue reading
Best Computer for Engineering Students
Engineering students need a computer that is portable, has good CPU speed, lots of memory, great graphics, and is affordable, which means that the laptops useful for most students simply won’t be the best computer for engineering students. Ironically, the laptops that make the best computers for students in engineering are gaming computers.
Why Gaming Computers are the Best Computers for Engineering Students
The reason why gaming laptops tend to be the best computers for engineering students is because the features that make these laptops good for gaming are also the same features that engineering students need, including:
- A fast CPU speed
- Plenty of hard drive memory
- At least 8GB of RAM
- Wi-Fi and Bluetooth connectivity
- Excellent graphics
- Reasonable cost
While good gaming computers aren’t cheap, unless someone is a real hardcore gamer, gaming computers can be acquired for between $1,000 and $2,000, which is cheaper and much more portable than a workstation for engineering students. In addition, while great for completing engineering tasks, gaming computers will also allow engineering students to play games, as well as do all the things that regular laptops do.
This allows engineering students to save and share their work, as well as use the Continue reading
Cloud Networking Transformation Ahead
Networking is undergoing a metamorphosis. Today’s operations are challenged to cope with the DevOps, NetOps, SecOps and CloudOps models that need consistent operations control. Why should enterprises care? How do you cope with decades of legacy and is change possible? Arista believes that the networking world is at the cusp of a transformation, significantly facilitated by the agile, dynamic and economic network models of the public cloud providers. They have proven the elegance of simple yet scalable designs that transform siloed networks for the data center, core, campus or branch PINs (Places in the Network) into east west PICs(Places in the Cloud). This new paradigm is a far cry from the traditional siloed network architectures that required applications to be assigned to specific servers or storage, causing fixed-function rigidity. Agility and high availability are pivotal foundations to building the new PICs.

TL&DR: It’s 2020, and VXLAN with EVPN is all the rage. Thank you, you can stop reading.
On a more serious note, I got this questions from an Johannes Spanier after he read my do we need complex data center switches for NSX underlay blog post:
Would you agree that for smaller NSX designs (~100 hypervisors) a much simpler Layer2 based access-distribution design with MLAGs is feasible? One would have two distribution switches and redundant access switches MLAGed together.
I would still prefer VXLAN for a number of reasons:

Rust: Constants, Variables, and Mutability – Oh My!
In the last post I wrote about my journey from Python to Go as my primary language, and how I am now exploring Rust. This will be the first in a series of posts on Rust, mostly written from this perspective. I realize not everyone is going to Rust from Go, but that’s my perspective, and it will be impossible to keep this perspective from showing through and making comparisons between Rust and Go or Python.AT&T Puts More Jobs on the Chopping Block
