# How To Check The Filtering Status Since our filter is DNS-based, the best way to check the filtering is the **nslookup** command. Here you will find the checking methods for different platforms.

Please note that settings take 5-7 minutes to apply. Stats and filtering status update every 10 minutes.

--- #### Windows Take a look at the video guide.
1. Open the "**Start**" menu 2. Type "**cmd**" 3. Select the suggested application - **Command Prompt** 4. Enter and run the command **nslookup -q=txt black.safedns.com** or **nslookup -q=txt black.safedns.com 127.0.0.1** if you are using the SafeDNS Agent

To check via IPv6 (if it was set up), use the command **nslookup -q=txt black.safedns.com 2001:67c:2778::3939**

Correct results should show your external IP address ("ip"), policy ID ("p"), and also SafeDNS Agent ID ("t") in case it is installed. If you see the results similar to *screenshot 01*, it means that the filtering is active. If the "p":0, check if the IP address in the Dashboard > Settings > Devices is added correctly.
