Since the default DNS services provided by ISPs are often slow and insecure, most people rely on alternative DNS providers - such as OpenDNS (208.67.222.222), Comodo DNS (8.26.56.26) and Google DNS (8.8.8.8), to speed up their Internet.
But if you use Cloudflare new 1.1.1.1 DNS service, your computer/smartphone/tablet will start resolving domain names within a blazing-fast speed of 14.8 milliseconds—that's over 28% faster than others, like OpenDNS (20.6ms) and Google DNS (34.7ms).

About those addressesWe are grateful to APNIC, our partner for the IPv4 addresses 1.0.0.1 and 1.1.1.1 (which everyone agrees is insanely easy to remember). Without their years of research and testing, these addresses would be impossible to bring into production. Yet, we still have a way to go with that. Stay tuned to hear about our adventures with those IPs in future blogs.For IPv6, we have chosen 2606:4700:4700::1111 and 2606:4700:4700::1001 for our service. It’s not as easy to get cool IPv6 addresses; however, we’ve picked an address that only uses digits.But why use easy to remember addresses? What’s special about public resolvers? While we use names for nearly everything we do; however, there needs to be that first step in the process and that’s where these number come in. We need a number entered into whatever computer or connected device you’re using in order to find a resolver service.Anyone on the internet can use our public resolver and you can see how to do that by visiting https://1.1.1.1/ and clicking on GET STARTED.

How to make Cloudflare's DNS Faster
There are many factors that affect how fast a resolver is. The first and foremost is: can it answer from cache? If it can, then the time to answer is only the round-trip time for a packet from the client to the resolver.
When a resolver needs to get an answer from an authority, things get a bit more complicated. A resolver needs to follow the DNS hierarchy to resolve a name, which means it has to talk to multiple authoritative servers starting at the root. For example, our resolver in Buenos Aires, Argentina will take longer to follow a DNS hierarchy than our resolver in Frankfurt, Germany because of its proximity to the authoritative servers. In order to get around this issue we prefill our cache, out-of-band, for popular names, which means when an actual query comes in, responses can be fetched from cache which is much faster. Over the next few weeks we will post blogs about some of the other things we are doing to make the resolver faster and better, Including our fast caching.
One issue with our expansive network is that the cache hit ratio is inversely proportional to the number of nodes configured in each data center. If there was only one node in a data center that’s nearest to you, you could be sure that if you ask the same query twice, you would get a cached answer the second time. However, as there’s hundreds of nodes in each of our data centers, you might get an uncached response, paying the latency-price for each request. One common solution is to put a caching load balancer in front of all your resolvers, which unfortunately introduces a single-point-of-failure. We don’t do single-point-of-failures.
Instead of relying on a centralized cache, DNS resolver, 1.1.1.1, uses an innovative distributed cache, which we will talk about in a later blog."

Why announce it on April first?
For most of the world, Sunday is 1/4/2018 (in America the day/month is reversed as-in 4/1/2018). Do you see the 4 and the 1? We did and that’s why we are announcing 1.1.1.1 today. Four ones! If it helps you remember 1.1.1.1, then that’s a good thing!
Sure, It’s also April Fools' Day and for a good portion of people it’s a day for jokes, foolishness, or harmless pranks. This is no joke, this is no prank, this is no foolish act. This is DNS Resolver, 1.1.1.1 ! Follow it at #1dot1dot1dot1
