Yet another Quadruple DNS?

dig google.com @1.1.1.1

Cloudflare?

Didn't find any news around it

Yeah, Cloudflare did a deal with Geoff Huston to use it. It’s reserved for “experimental use."

Many providers filter out 1.1.1.1 because too many people use it in their
examples/test code. I doubt that it's a usable IP/service.

Out of 1,000 RIPE Atlas Probes, only 34 report it as unreachable. Very good latency from those who can reach it..

There’s at least one vendor *cough* cisco *cough* that has used it as
captive portal IP.

I’m not sure I would try to use it on a client machine because you don’t
know if you’ll reach the internet.

If you know you’re not on a closed network, you could use it instead of
the list of usual suspects, like 8.8.8.8 4.2.2.1 9.9.9.9 etc.

having previously globally announce 1.1.1.1 ... and some other of it's
friends... not nearly enough people filter it.
We regularly saw ~10gbps+ of traffic to those prefixes.

1.1.1.0/24 and 1.0.0.0/24 both are APNIC's Lab Research Prefixes. APNIC,
probably doing some more data gathering on 1.1.1.1 and doesn't want to be
smashed with Gigs of traffic. Transit is still quite expensive in Aus :slight_smile:

Doubtful. This is most assuredly going to be a commercial production
recursive DNS service. Matthew (CEO) has said as much on Twitter:

Yep, they’ve been trying to put something together in this space for several years. Sounds like it may be close now.

I can’t say I envy them their task, as it will be very difficult for them to differentiate in that space, since they don’t have OpenDNS’s many years of experience and fine-tuning and security services, nor Google’s brand-recognition. Verisign have had a reasonably good commercial offering in this space for years, and hardly anyone’s heard of it, for instance. I believe even Neustar does. And they’re all DNS specialists, rather than web-content specialists.

Cute. I'm sure this engineering effort to centralize a distributed service will also go a long way to spur IPv6 adoption.

Also the very amusing

It's still a lot for IPv4. And it measures ony filtering, not hijacking
(which seems to exist, some probes get a DNS reply without the AD
bit, for instance).

Because of the heavy use of 1.1.1.1 in documentation, you can expect a
lot of networks to have trouble. Hey, 1.1.1.1 is even used in
Cloudflare's own documentation!
<Cloudflare API Documentation;

Why do we need this?

We already have 8.8.8.8 and 8.8.4.4.

And any reputable company or ISP should be running their own.

What purpose would this serve?

Less amusing, for a DNS service, the brokenness of reverse service:

Oddly, Matt, we agree again.

a message of 7 lines which said:

We already have 8.8.8.8 and 8.8.4.4.

And 9.9.9.9 and several others public DNS resolvers.

And any reputable company or ISP should be running their own.

I fully agree.

What purpose would this serve?

In Europe, the most common technique of censorship is through lying
DNS resolvers. So, in order to go to forbidden Web sites (music and
film sharing, for instance), many users switched from the ISP's
resolver (which implements the censorship) to a public resolver. See
my talk at NANOG
<https://www.nanog.org/sites/default/files/Bortzmeyer_Dns-Based_Censorship.pdf&gt;

Cloudflare’s website provides some more information: https://1.1.1.1/

According to Cloudflare’s CEO, we’ll have more news on 1/4, so in a few days.
https://twitter.com/eastdakota/status/979257292938911744

From their website I can see that it is a low latency and privacy oriented service. Now whether it’s actually needed, I think there’s place for it in the market. Currently in Greece, 8.8.8.8 is ~65ms away. This is 11ms away.
