How to Check VPN Connectivity for Any IP Leaks

A VPN masks your IP address and enables you to access geo-blocked content. It also encrypts your data and protects your IP and online activities from third-parties. But, there may be some technical flaws, and a VPN might leak your IP address or location. In case, if a VPN is not protecting your security then there is no use of it.

IP or DNS leaks are hard to detect, but you can follow our instructions to make sure that a VPN is working properly.

How To Check If VPN Is Working

The Most Common VPN Errors

A VPN might not be performing well because of many reasons. But, most of the VPNs compromise users’ security because of the IP or DNS leaks. Most common VPN leaks are:

  • DNS Leak

Always try to avail a VPN service that guarantees protection against IP/DNS leaks. A DNS leak is a VPN security flaw. A VPN fails to hide DNS requests and reveasl them to the ISP. It means that your ISP servers know what websites you are visiting and who you are. If anyone is prying your traffic, then he can easily access your information and it might lead to the DNS control attack.

  • IP Leak

Your security is at high risk if your VPN is not concealing your IP address. A VPN masks your original IP with its own IP, so no one can see your real IP address, and fails to know what you are visiting on the internet. However, if a VPN fails momentarily to protect your IP then it causes an IP leak. In case of the IP leak, any hacker can easily trace your location and websites that you are visiting. The IP leak may occur because of the incompatibility of IPv4 and IPv6 protocols.

  • Web Real-Time Communication Leak

WebRTC is designed for the top-performing browsers e.g. Chrome, Firefox, Opera and etc. It supports the voice and video chat, but some websites misuse it and add extra lines of codes to detect a user’s real IP address. These websites identify user location and provide geo-restricted content only.

All of the mentioned leaks are a VPN’s technical flaw that you can resolve, once you detect them. Follow these instructions below to detect each error.
