Check Your DNS Server


To check what DNS Server you are using on Windows computer, simply open up the command prompt and do nslookup any website say, google. However, for some unknown reason, this doesn’t work for me. (I tried this command on two windows computer and go unexpected error message).

So, next thing, you can do is, type the following command on your cmd.

ipconfig /all | findstr /R "DNS\ Servers"



Mac and Linux

To check what DNS Server you are using on any Mac or Linux based computer, simply open up the terminal and do nslookup of any website. For example, type in the following command.





There are a handful of Android network scanner apps in the market, that lets you see you DNS. I suggest network info II. At the time of writing this post, the app is free, no ads and works like a charm. Simply download it from play store, open it go to WiFi tab, there you’ll see DNS1 and DNS2 entry.



Network Analyser, is a free IOS app that shows useful information about your network. There are two versions of this app, the full version cost $3 but for our need the lite version (ad supported) is sufficient.
