Debug Your DNS

We love good content from all around the web and the authors that are writing on the intricacies of networking and infrastructure design. Today we found an awesome post on debugging DNS. We’re big fans of DNS at Panopta and if you haven’t seen our series on DNS, you can start with the first post here.

The article, ‘Debugging DNS’ from Ole Michaelis is a great primer on using tools like whois and dig to get detailed information about DNS resolution through all the links in the resolution chain. These command line utilities have been around for quite a while, but are still critical tools to know about and use for troubleshooting. Check it out for yourself!
