How to find my DNS Server address in Windows 7

You want to open "Run" then type

cmd.exe

In the command prompt enter this command

C:\>ipconfig /all | findstr /R "DNS\ Servers"

The output should look something like:
enter image description here

If you know your public IP address simply enter in a command prompt window:

nslookup <your public IP>

You can also specify the name server to check against by appending it to the above command.

You can get your current IP address from sites like http://whatismyip.com

Personally, I prefer this approach:

echo | nslookup | findstr "Default\ Server"

It will print the name of your default DNS server in the shell
