How does a DNS server work ?
All websites can be accessed by typing in the site's URL, for example: facebook.com.
However, a URL is only the translation of the website's IP address, for example: 43.194.30...
Your browser may remember a number of IP addresses, and government or third-party censorship may intercept a DNS request and redirect you to blocked or spoofed content.
RingVPN servers use their own private DNS system: when you are connected to RingVPN, your DNS activity has the same encryption protection as your browsing; no man-in-the-middle attack is possible.
