There are more and more people start using VPNs(Virtual Private Networks) for online protection or unblock websites these days. A VPN is a fantastic tool to protect your privacy online and give you the ability to access any content you want. By building an encrypted tunnel that passes through all of your internet traffic, a VPN masks your IP address and hides your online traffic, giving you an extra layer of protection.
When it shows on the applications that you are “connected”, but actually it is not doing its job sometimes, it could be possible that your identification and location is exposed to government and third parties.
Moreover, some websites also block VPNs when they find out the same IP address has been used by many accounts. If the IP addresses belonged to the VPN service provider are leaked, even if you are using a VPN, it doesn’t work for unblocking websites such as Netflix, Hulu or other streaming websites.
How do I know if my VPN is working?
Before showing you how to check out if the VPN actually works, you need to know about how it is leaked in the following ways.
- IP address leak
IP address is like your passport to the internet, it tells where you are from and let you access the internet. When you use the VPN, it hides your real IP address, if in the testing, when you are still connected to your VPN but it still shows your real IP, then you have an IP leak.
- DNS leak
DNS or the domain name system is used to translate domain names such as www.XXX.com into numerical IP addresses e.g. 220.127.116.11.
DNS leak means that your DNS requests to be revealed to ISP DNS servers, despite the use of a VPN service attempts to conceal them. If the testing result shows your “reallocation” that belongs to your ISP, then you have a DNS leak.
DNS leaks are a major threat to privacy as the anonymity network can provide a false sense of security when private data leaks.
- WebRTC leak
WebRTC stands for web real-time communications. A WebRTC leak is when your real IP address is exposed via the WebRTC feature of your browser. This leakage will de-anonymize you using WebRTC APIs, even if your VPN works properly
How to test IP/DNS/ WebRTC leaks?
Here we collect some testing websites that are safe to use.
IP Leak Test
1. Write Down your real IP address
2.Here are some websites that you can check your current IP address:
3.Compare your IP addresses when connecting to different servers with the VPN, if it only shows your real IP and your real location, then your VPN is not working at all.
