CloudFlare DNS and how and why to use them

In our articles we have often suggested using Google's DNS, because they are significantly faster than those provided by the providers and allow you to avoid some territorial blocks. CloudFlare recently launched its own DNS that wants to oust Google's from the hearts of fans, and beat it in terms of security and speed.

What are DNS servers?

DNS servers, are also called resolvers, they have a fundamental function in the Web we know. In reality, each page available on the Internet would be identified and reachable through its unique IP address (GiartheniBlog's address is, but this being a series of four thegits separated by periods is not exactly intuitive and easy to remember.

This is why DNS servers were born that associate a text string to the IP, what we commonly call address (for example ours is All our web browsing goes through these servers, which then are crucial for the protection of our privacy, For the our safety and for ours browsing speed. A slow DNS server will slow down the preliminary phase for each page to load, and therefore seriously impact our browsing experience.

Our browsing traffic passes through the DNS, so their safety is really important. Often the DNS provided by the telephone operators, are deficient on this front, not offering strong encryption or support for the DNSSEC protocol, thus making them vulnerable to thefferent types of dangerous attacks.

The advantages of choosing DNS and offered by CloudFlare

The DNS servers offered by CloudFlare are very thefferent from those of the operators, because they support the DNSSEC protocol and do not in any way track the pages visited by users for commercial purposes. The company also claims that all user browsing session logs will be deleted within 24 hours of use.

The lack of CloudFlare tracking, and attention to performance make this new resolver an interesting alternative to other famous resolvers such as OpenDNS and Google's DNS.

The metheum site, after the launch, thed an interesting and in-depth speed test using the open source tool DNS Performance Test, from which it emerged that the CloudFlare resolver was on average faster than its competitors around the globe (with a 4,98 ms load average far faster than Google DNS which stopped at 16,44 ms).

You can make a quick test yourself using the handy and lightweight DNS Jumper program. My proof, as you can see from the screenshot, has shown a clear winner.

Like other international DNS addresses, this resolver it allows to avoid regional blockades imposed by the juthecial authorities on some sites. So it allows you to access without problems even portals that are unreachable through the DNS provided by the providers.
