DNS Leaks Explained | NordVPN


What are DNS leaks and how do they threaten
your privacy? To start off, the DNS, or the Domain Name
System, is responsible for converting domain names into IP addresses. For example, whenever you enter “nordvpn.com”
into your browser, it first contacts a DNS server and requests the unique IP address
of the site. When you’re browsing without VPN, such requests
usually go through DNS servers owned by your Internet service provider. This way, your ISP can monitor your online
activity. When you’re browsing with VPN, DNS requests
are routed through DNS servers owned by your VPN provider, such as NordVPN, so that your
ISP can’t see what you do on the Internet. So when do DNS leaks happen? Even if you’re connected to VPN, there is
a risk your system will revert to the default DNS server. This may happen if your VPN is configured
improperly, or the VPN service you’re using doesn’t have its own DNS servers. Basically, a DNS leak means that your internet
traffic is ‘leaking’ outside the secure VPN tunnel – that is, your private online
data is exposed. The best way to avoid this is to use a VPN
service that owns its DNS servers and offers adequate protection from leaks. NordVPN has implemented a DNS leak protection
technology to prevent any unencrypted queries going outside the secure VPN tunnel. So with NordVPN up and running, you can keep
calm – your private data will stay private. If you want to learn more about online security,
