DNS is a Domain Name System which connects your request for www.example.com<\/strong> to the server’s IP where www.example.com<\/strong> resides. In other words, when you enter in your browser www.example.com, your PC connects to the authoritative DNS server for this domain, requests destination IP and retrieve website’s content from the hosting server.<\/p>\n\n\n\n

What is DNS leak and why it can be a problem?<\/h2>\n\n\n\n

When you connect to the VPN (check this article<\/a> on how to connect to the OpenVPN) your traffic is being encrypted and routed through a VPN server. So, if somebody intercepts your traffic he will only be able to see how you connect to a VPN server and no information about what websites\/servers you visit. This changes with DNS leak. When you connect to the VPN, your PC should also request new DNS from the VPN and update it’s network config. For different reasons, your PC may fail to update the DNS during connection to the VPN and when you will be browsing Internet, your DNS requests will go through your ISP’s (Internet Service Provider) DNS server which will reveal which websites\/servers you access. Your traffic will still be encrypted but your privacy will be compromised at this point.<\/p>\n\n\n\n
