The Domain Name System (DNS) is a fundamental Internet technology. Network emulators like Cloonix offer a way for researchers and students to experiment with the DNS protocol and with the various open-source implementations of DNS, such as BIND.
In this post, I will install Cloonix from the Github source code repository. I will run the Cloonix DNS demo script to create a simple DNS scenario and then run some experiments with DNS. Along the way, I will demonstrate some of the new Cloonix version 33 features.
In this demonstration, I am using Cloonix version 33. I last used Cloonix when it was at version 29 and version 33 offers some significant changes and improvements. Compared to version 29, the major changes in version 33 are:
Earlier I wrote about some fundamental principles that I believe apply to any form of automation, whether it’s network automation, or even building a virtual factory.
One of the most important concepts in mature automation is autonomy; that is, a system that is more or less self-sufficent. Instead of relying on human beings for input, always try to provide that input with yet another automated piece of the system. There are several benefits to this approach:

IaaS is still small, but Oracle has big plans for it.
Bell Canada will use SDN for its wireless and wireline networks.
Big data could help SDN automate the WAN and the data center.
