This is going to reveal my lack of networking knowledge but how does a company get an IP like 1.1.1.1? A bucket load of cash?

Help from / collaboration with APNIC: https://blog.cloudflare.com/announcing-1111/

Geoff Huston is the chief scientist at APNIC. I highly recommend checking out some of his talks on yourtube.

> but I also doubt that enough people will understand this nuance for it to really matter. Certainly that's the first step. There's options for the second step. But advertising seems like it would be the most powerful. "Why use us over AT&T? Because you're not getting the Internet. You're getting what AT&T decides you should look at." "We don't block Netflix or Hulu or a whole host of other streaming services, unlike…

Who's advertising this when AT&T has a legal monopoly or duopoly in your town?

The arguments for anti-net-neutrality has basically come down to "let the free market sort it out." I don't agree with that, but if we can't have net neutrality, at least define to the customers what the "internet" means.

And in that case, the town just lost it's internet. What makes you think the residents won't remember this come election day?

1.1.1.1 was working for me on AT&T after Cloudflare released 1.1.1.1, then shortly after that it ceased working. Maybe the firmware update has a bug, but it's very suspiciously timed. Notice that the OP is dated April 2, while 1.1.1.1 was released April 1.

I was using 1.1.1.1 with AT&T Fiber and it stopped working. I didn't really question it, I figured maybe something went down at Cloudflare so I just switched my Mac back to using the defaults again. It never even occurred to me that AT&T might be blocking it. Maybe stupid question, but why would AT&T block it?

Same thing happened to me using at&t fiber.

If they were so determined to block it, why would they do it in firmware and not upstream? I think people are reading too much into this.

It's cheaper to do it on the mobile?

I'd say there is a 98% chance this is a bug in some firmware and a 2% chance AT&T is intentionally trying to block Cloudflare DNS. I get why people are paranoid about ISPs blocking content and net neutrality, but let's not cry wolf prematurely. The technical details here strongly suggest a bug rather than intentional blocking of 1.1.1.1 DNS traffic.

I really hope that's the case, was 1.1.1.1 allocated before CF acquired it? Was 1.0.0.1 also blocked?

Having it seem like a bug would be an effective way to block it intentionally. The timing of such an unusual regression is suspicious. The fact that 1.0.0.1 is also blocked is also suspicious.

> Having it seem like a bug would be an effective way to block it intentionally. Just like how only the true messiah denies his divinity, it doesn't give innocent bugs much of a chance. In fact, now we can show that all bugs are suspicious, with apologies to the interesting number paradox: The least intentional looking bug is the most effectively hidden, and therefore should probably be suspected of being intentional…

That's not my point. It's suspicious because of its specificity and timing; its bug-like presentation isn't evidence either way.

How is this not illegal?

Let's give them the benefit of the doubt, it's probably incompetence ;)

Incompetence or intent, if there was a penalty for this kind of thing you'd see it happen a lot less.

What's that saying about not attributing to malice, what is more easily explained as stupidity or incompetence or whatever? (Occom's Razon and all that). AT&T routers also don't let you use a 10.x address at home (possibly to prepare for carrier grade NAT, although there is an official 100.x address reserved for that; so fuck you ATT). I'm so sick of my AT&T router/modem for various other reasons. I hate how you are…
