Sweden-based VPN provider Mullvad announced today that its public encrypted DNS servers run fully in RAM. The announcement comes less than two months after Mullvad completed the migration of its VPN infrastructure to RAM.
The main benefit of running servers in RAM is that all traces of activity on disk are removed. Mullvad uses its own custom infrastructure to power its services and engineers are constantly working on improving it.
Encrypted DNS, widely known as DNS over HTTPS, protects DNS traffic by encrypting it. Network spies, such as the ISP or malicious actors, don’t get cleartext information anymore when the security feature is enabled.
Data is encrypted, which prevents third-parties from finding out about the sites that you access while connected to the Internet.
Mullvad’s encrypted DNS solution is available free of charge for everyone. The company advises customers of its DNS service, which is available for a flat-fee of 5 EUR per month, not to use the encrypted DNS service as the DNS resolver of the VPN server is handling this automatically. The performance of connections could be slower, if users make the switch.
Interested users may check out Mullvad’s extensive guide on setting up the encrypted DNS solution on their devices. The company operates several different DNS solutions. You may configure various content blocking options, besides the unfiltered DNS server option.
Here is the overview of the available hostnames and their content blocking level:
- No content blocking: dns.mullvad.net
