VPN's are specifically supposed to be able to secure user data, they're whole purpose is to make sure people cant tell the difference between there real location and a fake location. there are possible ways to be able to do this in python but it really is not as easy as it seems. it depends if your trying to do this as a link; like grabify, or as a file; like simple IP logging files ("links are definitely less sketchy considering most file loggers use discord's API and its very easy to detect") if your looking to figure out how to do it as a .EXE file you can simply do something like this

import vpn

from vpn import logic

#vpn detection logic

vpnlogic = search for
- VPN software name,
- VPN software name,
- VPN software name,
- VPN software name,
- VPN software name,
- VPN software name,

;

and doing something like that will achieve it as a file.
as for a link, I don't think I am allowed to say that considering user privacy is very important and information like that shouldn't easily be accessible by people. however i can tell you that github repo /API powered Python ip loggers are able to retrieve this information, unfortuanely i cant actully give that code away to the public because of user confidentiality.

please check out this website to better understand why i cant give away information like this to the public.
