The Wiert Corner – irregular stream of stuff

The dig (domain information groper) command under unix/Linux is a great way to help verify that a DNS host like BIND is working properly.

A few of my servers are Linux, but most of my desktops usually are Windows, so I was happy to find the Using the dig dns tool on Windows 7 article by Dan Esparza explaining there is a Windows version.

So I:

1. Downloaded the Windows version of BIND (I took the BIND 9.9.2-P1 ZIP file)
2. Unzipped that into my C:\BIN\BIND directory
3. Ran this command, just like I would on a Linux box:
   dig @192.168.171.214 pluimers.com
4. Checked the below output to the zone configuration on the openSUSE box serving the DNS for my domain
