How to trace your DNS queries

.

Hi again

In this blog I just to introduce you with very useful command to trace the dns queries. as you know the DNS queries has two main categories which are Iterative and Recursive. sometimes in your network you will be faced with the DNS records problem. for Iterative queries ( having delegation in your dns zones to other dns servers)  the best way that you can understand which DNS server is causing the error is “dig” command. it can be installed on both Windows and Linux OSes. it has many options that I am really interested to tell you what are they but unfortunately time is little.

the command you should use is :

dig @your Caching Only Name Server or Iterative Dns Query Server IP Address +trace www.mehdibehamin.com

I am always waiting for your question about the DNS.

Reference : The dig manual
