Can a VPN usage be detected?

Post by amme » Sun Dec 06, 2020 11:38 pm

Hello everyone!

I'm currently discovering how to use VPN and how reliable it is. Are there tools that can detect I'm using a VPN?

I came across some IP location tools that show not only IP, country, region but if VPN use is true/false. Like this for example

It returns the security part among other data:

"security": {
"is_vpn": false

I checked and when I use VPN it returns the masked IP data and shows "is_vpn": false, so doesn't recognize that I use VPN. However, is it possible that other geolocation services may detect VPN?

there are some sites that could detect VPN usage. However there are also top notch VPNs that has a feature to counter this.

VPN clients can be difficult to detect as they typically use a port such as 443 over UDP or TCP which is normally open on a firewall. ... Once you select a VPN server, an encrypted connection is created between your client and the VPN server. All of your Internet bound activity is then routed through this VPN connection.
