What is a DNS leak and how do I fix it?



What is a DNS leak?
When you're connected to our VPN service, you're automatically using Google DNS servers instead of your internet providers DNS server. This ensures that your ISP cannot view what domains you are accessing. However, sometimes your system settings might revert back to your ISPs DNS servers, resulting in your ISP being able to see what websites you are visiting! 

How do I check if my DNS is leaking?
One way to check if your DNS is leaking is performing a check at http://www.dnsleaktest.com.

What can I do to prevent a DNS leak? 
Our client is set up to prevent DNS leaks but having your local DNS servers set to your router gateway (usually 192.168.1.1) can override our settings as we can't block your internet gateway :)

Change the DNS server on your computer to 8.8.8.8 and 8.8.4.4 (Google DNS) OR 208.67.222.222 and 208.67.220.220 (OpenDNS)
