Detect if the user uses a VPN

Today I’m gonna show you how you can check an user’s IP and see if they are using a VPN without any extension and without a limit.

Step 1

Drag 2 web component into your screen.

Go into the blocks screen, and drop the following blocks:

Strange :thinking: seems like they changed their API or smth…
I found another API: https://proxycheck.io/
You can parse the result with the JSON component, and get the “type”

Here with nordvpn:

I am connected to the belgium server, and you can see that in the “type” return “VPN”
image (I’m using ubuntu so yeah)

Without a VPN it will output "type": "Residential"

So from this you can check if the value of “type” is a VPN.

Their server is probably hosted with Azure

#7

Maybe :thinking:
Well you just have to test if “type” is “Residential” maybe it’ll work better

#8

Please make a Extension

#9

(https://api.ontstudios.com/proxy/check.php)

Ssarch the extensions directory for an extension

You may give this a try:
com.django.djvpnchecker.aix (5,4 KB)

Edit: This is no official extension, just a helper extension for you to test if this solves your issue.

Is this the first time you are publishing this extension?
Up to now it is not in the extensions directory…
Could you please start a new thread in category #extensions to publish the extension including a short documenation?

Thankyou and please do documentation for this as suggested by Mr.Taifun @Taifun @Django_s_Android_App

This extension has only one method that throws out a boolean, True or false.
But the question is:
Does it solve your problem or not?
BTW, in times of restriction to 5 extensions for a non Premium user an extension shouldn’t have only 1 method :wink: So I wouldn’t release it.

don’t worry about that…

Can i use it in this way ? or can you please show your blocks arrangement… @Django_s_Android_App

#17

No, you have to use boolean true or false blocks or just remove them completely like this

if DjVpnChecker.IsVpnActive
then close application
else open another screen ...
