Best sites to check for IP leaks 2018

The current activities in the cyberspace require everyone surfing the internet to use some kind of cloaking technology. The one available at the moment mostly relies on VPNs and other services which offer anonymity and privacy. But these techniques don’t protect our anonymity at most times due to various leaks such as DNS leaks and IP leaks; both IPv4 and IPv6 leaks.

IP leaks

Most IP leaks are as a result of our web browsers and sometimes the Operating System (OS) as a whole. In browsers, leaks occur due to something called Web Real-Time Communication (Web RTC). Web RTC is an interface or mini-program in our browsers that help in facilitating various functions such as chats, video calls, file sharing and activities which revolving communication. Even if you are protected, attackers can reveal this web RTC to reveal your IP address (leak) and hence perform more complicated attacks. At times, the OS may also leak the IP especially when you are using services that hide your IP. This is possible as the OS can get confused when sending an IPv4 request and will resolve the confusion by using the default DNS provided by your ISP. This usually happens in machines running the Windows OS. Other times for instance when using a VPN, your connection may drop and hence your IP may not be masked anymore. In 2017 we reported about the the Tor IP leak, which you can read more about here.

Nowadays, most VPNs offer protection against leaks that occur during connection drops by using a kill switch. When activated, a kill switch will block any outgoing/incoming traffic until the VPN connection is up and running again. Generally, the VPNs are also equipped with other tools that protect against DNS and IP leaks. But due to the underlying OS, the leaks happen anyway. Most people don’t know if there are IP leaks in their systems but thanks to the following websites, now you can know if your IP is leaking. All you need to do is to know your IP by first doing a test on the sites. Then connect to VPN server and note their IP address. Perform the test again; If the test does not show the VPN IP, then you know that you have an IP leak. I
