:marseynull: Someone PISSED OFF Cloudflare, but NOT for the reasons you think :!marseykernelpanic:

https://www.ctrl.blog/entry/cloudflare-ip-blockade.html

Orange Site

Generated by TLDR This:

I don’t know what I did wrong, but I’ve angered one of the titans of the internet!

Unfortunately, not every web request can run the Cloudflare challenge page.

So, my original offense might not even have been against Cloudflare.

I had a terrible experience online for almost a week before everything cleared up.

The extension provides, what Cloudflare claims, is a privacy-preserving alternative to resolving CAPTCHA s on its challenge pages.

This might have affected the situation, but again, I have no insight into Cloudflare’s automated decision-making.

How would domain registration be handled? Would a single company implement its own ENS-like system? Wouldn't this just lead to a similar issue whereby a single company is making these host-limitation decisions, just with a more distributed infrastructure? If not, how does the overall system decide when a domain registration is "valid"?

I don't know why you're thinking of this as a hypothetical, it's a system that exists, you could just read the whitepaper.

I was being lazy and didn't want to research on my own. I also like to think this stuff out on my own to get an intuitive understanding.

To answer my question:

The root node is presently owned by a multisig contract, with keys held by trustworthy individuals in the Ethereum community. We expect that this will be hands-off, with the root ownership only used to effect administrative changes, such as the introduction of a new TLD, or to recover from an emergency such as a critical vulnerability in a TLD registrar.

These key holders basically function as a hand-off ICANN.

Top-level domains, like ‘.eth’ and ‘.test’, are owned by smart contracts called registrars, which specify rules governing the allocation of their subdomains. Anyone may, by following the rules imposed by these registrar contracts, obtain ownership of a domain for their own use. ENS also supports importing in DNS names already owned by the user for use on ENS.

TLDs are handled by smart contracts, which presumably establish the pricing rules for purchasing names within that TLD. My understanding is that these domain name purchases necessarily require compatible cryptocurrencies due to the algorithmic smart-contract enforcement. This seems like a major barrier to more widespread implementation.

It would be an absolute nightmare to try to shift the existing internet DNS infratructure onto this protocol.

Also, an interesting snippet in the FAQ:

Over time, we plan to reduce and decentralise human control over the system. Powers still held by the ENS root, such as those to set pricing and renewal conditions for domains, will be decentralised as robust systems become available to permit doing so.

Emphasis mine. This is indicative of the performance issues I was referring to previously. Decentralizing this functionality necessitates more information exchange between peers, thus further increasing bandwidth demand by this protocol.

Overall, though, fascinating stuff. I'm glad I looked into it.

Nameprep and handling improper naming is now pushed onto all consumers. There's no way for a resolver to handle this problem itself. I'm not sure if this is how it currently happens with the current DNS infrastructure, but it seems like another scaling issue for this protocol.

This seems like a pretty trivial thing for browsers to do.

I misread it, the resolver handles the nameprep but the protocol itself requires that nameprep be done beforehand. In short, the protocol can encode bad data into the blockchain. This leads to problems like this.

Also, upon further reading, I see that the name resolution does not take place within the chain. The blockchain stores an owner and resolver for a namehashed entry, but the mapping of the name to an address takes place within a server listed as the resolver within the registry blockchain. When writing my previous comments, I was under the impression that address resolution took place within the blockchain.

Effortposts made by SN Chads

Guidelines:

What to Submit

On-Topic: Anything that good slackers would find interesting. That includes more than /g/ memes and slacking off. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual laziness.

Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably lame.

Help keep this hole healthy by keeping drama and NOT drama balanced. If you see too much drama, post something that isn't dramatic. If there isn't enough drama and this hole has become too boring, POST DRAMA!

In Submissions

Please do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It should be explicit in submitting something that you think it's important.

Please don't submit the original source. If the article is behind a paywall, just post the text. If a video is behind a paywall, post a magnet link. Fuck journos.

Please don't ruin the hole with chudposts. It isn't funny and doesn't belong here. THEY WILL BE MOVED TO /H/CHUDRAMA

If the title includes the name of the site, please leave that in, because our users are too stupid to know the difference between a url and a search query.

If you submit a video or pdf, please don't warn us by appending [video] or [pdf] to the title. That would be r-slurred. We're not using text-based browsers. We know what videos and pdfs are.

Make sure the title contains a gratuitous number or number + adjective. Good clickbait titles are like "Top 10 Ways to do X" or "Don't do these 4 things if you want X"

Otherwise editorialize. Please don't use the original title, unless it is gay or r-slurred, or you're shits all fucked up.

If you're going to post old news (at least 1 year old), please flair it so we can mock you for living under a rock, or don't and we'll mock you anyway.

Please don't post on SN to ask or tell us something. Send it to [email protected] instead.

If your post doesn't get enough traction, try to delete and repost it.

Please don't use SN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity. If you want to astroturf or advertise, post on news.ycombinator.com instead.

Please solicit upvotes, comments, and submissions. Users are stupid and need to reminded to vote and interact. Thanks for the gold, kind stranger, upvotes to the left.

In Comments

Be snarky. Don't be kind. Have fun banter; don't be a dork. Please don't use big words like "fulminate". Please sneed at the rest of the community.

Comments should get more enlightened and centrist, not less, as a topic gets more divisive.

If disagreeing, please reply to the argument and call them names. "1 + 1 is 2, not 3" can be improved to "1 + 1 is 3, not 2, mathfaggot"

Please respond to the weakest plausible strawman of what someone says, not a stronger one that's harder to make fun of. Assume that they are bad faith actors.

Eschew jailbait. Paedophiles will be thrown in a wood chipper, as pertained by sitewide rules.

Please post shallow dismissals, especially of other people's work. All press is good press.

Please use Slacker News for political or ideological battle. It tramples weak ideologies.

Please comment on whether someone read an article. If you don't read the article, you are a cute twink.

Please pick the most provocative thing in an article or post to complain about in the thread. Don't nitpick stupid crap.

Please don't be an unfunny chud. Nobody cares about your opinion of X Unrelated Topic in Y Unrelated Thread. If you're the type of loser that belongs on /h/chudrama, we may exile you.

Sockpuppet accounts are encouraged, but please don't farm dramakarma.

Please use uppercase for emphasis.

Please post deranged conspiracy theories about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and dang will add you to their spam list.

Please don't complain that a submission is inappropriate. If a story is spam or off-topic, report it and our moderators will probably do nothing about it. Feed egregious comments by replying instead of flagging them like a pussy. Remember: If you flag, you're a cute twink.

Please don't complain about tangential annoyances—things like article or website formats, name collisions, or back-button breakage. That's too boring, even for HN users.

Please seethe about how your posts don't get enough upvotes.

Please don't post comments saying that rdrama is turning into ruqqus. It's a nazi dogwhistle, as old as the hills.

Miscellaneous:

The quality of posts is extremely important to this community. Contributors are encouraged to provide high-quality or funny effortposts and informative or entertaining comments. Please refrain from posting the following:

  • Boring wingcucked nonsense nobody cares about that belongs in chudrama

  • Normie shit everyone already knows about

  • Anything that doesn't gratifify one's intellectual laziness

  • Bimothy-tier posts

  • Anything that the jannies don't like

Jannies reserve the right to exile baby ducks from this hole at any time.

We reserve the right to exile you for whatever reason we want, even for no reason at all!
