The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

I am not big in talking about politics, but this blog post does a detailed analysis of some claims researchers made linking Donald Trump's e-mail servers to a russian bank server. I figured maybe some folks here who actually understand how DNS works would find it interesting.

tl;dr the logs look fabricated to damage Trump.  Thanks for sharing this.  It is interesting to see the lengths at which this author is able to explain this information and leave it for us to decide that 'fake news' is prevalent.

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

It's always exciting around here! We're thrilled to expand our partnership with ConnectWise to offer customers better protection and performance. To get insight into why this matters, we sat down with George Anderson, Webroot’s product marketing director for business solutions, and Gavin Gamber, vice president of Channel Sales and Alliances at ConnectWise.
 
What is DNS Protection? Why is it important? Why do ConnectWise partners need this?

For the past few months I've been a Beta tester for a new service called DNS Spy.  It's a service that Monitors, validates and verifies your DNS configurations.  

It might be worth a look if you are looking for something that monitors your External DNS.  Link below:

Haven't tried it out yet, but this looks cool.

Why DNSCrypt is so significant
In the same way the SSL turns HTTP web traffic into HTTPS encrypted Web traffic, DNSCrypt turns regular DNS traffic into encrypted DNS traffic that is secure from eavesdropping and man-in-the-middle attacks.  It doesn’t require any changes to domain names or how they work, it simply provides a method for securely encrypting communication between our customers and our DNS servers in our data centers.
