VPN detection API is a tool that allows an internet service provider to identify and limit traffic that has been masked by a VPN. This can help reduce the risk of a network breach. However, it is not always easy to determine if an IP address is masked. You may need to use a packet capture device to get a thorough picture of the IP.

How do you check if the IP is used with VPN?

In addition to identifying VPN users, it can also block fraudulent transactions. This can be done through an automated system, or a human observer.

The Free API offers a comprehensive check for both proxy and VPN detection API. It also detects fraudulent IPs. For more advanced tests, you may need to use a packet capture device or even a router.

Government agencies can also obtain data from the Internet Service Provider (ISP) to find out whether a user is using a VPN. This data can be used to trace the users online activity back to them.

Some providers even resell hacked SSH connections. They can be used to spoof a user’s IP and change their virtual location.

There are also tools that allow you to bypass proxy detection. These include built-in browser tools and third-party applications. While these methods can be effective, you should read information about them before implementing them.

You can also use the IPQS protocol to analyze TOR connections and detect account takeover attempts. It can also perform deep packet inspection to detect VPN traffic.
