Quad9 DNS: As we mentioned yesterday, the Global Cyber Alliance released a new free Domain Name Service resolver with unusually strong security and privacy features.
The Domain Name Servers (DNS) are necessary for your access to Internet. Each computers or mobile device uses DNS to access websites, email servers, APIs, and other services.
You know that you can configure your DNS to not use the ones your ISP has given you. You can for example use Google DNS (8.8.8.8) or the OpenDNS service. According to our publication yesterday, however, you have one more choice from IBM.
It's called the Quad9 DNS service and can block malicious domains for anyone using it from a large list compiled by IBM. This will give your computer an extra layer of protection.
The service provides the following DNS:
- Secure IPv4: 9.9.9.9 Blocklist, DNSSEC, without EDNS Client-Subnet
- Unsecure IPv4: 9.9.9.10 without blocklist, without DNSSEC, sends EDNS Client-Subnet
- Secure IPv6: 2620: fe :: fe Blocklist, DNSSEC, without EDNS Client-Subnet
- Unsecure IPv6: 2620: fe :: 10 without blocklist, without DNSSEC, sends EDNS Client-Subnet
Below we will see how you can add the DNS resolvers of the service to a computer running Linux.
We will do it simply, from the Network Manager without editing the system files. (/etc/resolv.conf or / etc / network / interfaces or /etc/systemd/network/05-eth0.network I guess is called eth0. Routes vary depending on the distribution you use.)
But let's see how it is done through the Network Manager application.
Open the app, and follow the steps below. From the icon with the tools (1) I opened my wired settings, turned off Automatic (2) and added DNS 9.9.9.9.
Apply when done.
Repeat the process with your wireless connection.
For those who are interested and have IPv6, there is also an IPv6 Quad9 resolver: 2620: fe :: fe
After the plugins do a reboot and you are ready.
