Cricket Liu's DNS Advisor
THIS FREE TOOL, DEVELOPED BY INDUSTRY AUTHORITY CRICKET LIU, TESTS THE CONFIGURATION, CONSISTENCY, AND SECURITY OF YOUR EXTERNAL DNS CONFIGURATION.

In all, DNS Advisor tests over 50 different facets of your zone and name servers' configuration and interprets the results—providing valuable insights you can use to implement DNS best practices in your network.

  • Checking for open recursion that can leave servers vulnerable to cache poisoning and DDoS attacks
  • Verifying that you're running a recent and secure version of your name server software, which can help prevent network downtime
  • Identifying single points of failure that can compromise network availability

At the end of the test, you will have an opportunity to download an assessment report in PDF with an executive summary on how to address any shortcomings in your environment.
