How to check a remote servers DNS version

To check a remote servers DNS version simply run the following command from Linux:

$ nslookup -q=txt -class=CHAOS version.bind. 0 www.server-you-want-to-check.com

or on Windows:

$ nslookup -q=txt -class=CHAOS version.bind www.server-you-want-to-check.com

The results will note the BIND or DNS version number, for example: version.bind    text = “9.2.4”
