VPN connections reroute internet traffic, which can make it difficult for websites to determine their users’ location. Detection tools can help identify VPN users by checking the IP address against blacklists of malicious or proxy IP addresses. Other methods, such as reverse DNS lookups and examining the hostname associated with the IP address, can also indicate that the user is using a VPN.

How to verify if an IP address is a VPN connection common method to verify if an IP address is a VPN connection involves looking at the connection speed. Since VPNs reroute traffic, they can cause internet speeds to decrease slightly. However, many VPN solutions include features that improve network performance and speed up internet connections. To check your connection speed, visit a website such as WhatIsMyIPAddress.

A VPN can also be detected by analyzing the IP address’s time zone mismatch. VPNs typically connect to servers located in different geographic regions. If a visitor visits a website from Mexico, Japan and England in the same day, the website operator can determine that the visitor is likely using a VPN.

There are also APIs that can efficiently identify VPN usage based on a variety of factors such as risk analysis, location and behavior history. These tools can be used by companies to identify and manage VPN connections, mitigate security risks and ensure compliance with regional regulations. However, it’s important to note that most of these detection techniques are not foolproof and can produce false positives if the wrong criteria is used. For this reason, it’s important to utilize multiple detection methods when identifying VPN usage on your networks.
