    If you can’t remember the IP address of every site you’d like to visit, you don’t deserve the internet.

          Oh, I forgot about DNS servers. Then I remember:
          8.8.8.8 - Google
          9.9.9.9 - Quad9
          1.1.1.1 and 1.0.0.1 - Regular Cloudflare
          1.1.1.2 and 1.0.0.2 - Cloudflare “Malware blocking”
          1.1.1.3 and 1.0.0.3 - Cloudflare “Malware and adult content blocking”
          45.90.30.180 and 45.90.28.180 - NextDNS

          And I think 2960:fe::fe is also Quad9, but I’ll have to check. Nope, it’s 2620:fe::fe. So just the ones above.

      It’s not insecure at all, quite the opposite. Also with DoH, it blends into regular traffic.

        DoH is blocked in China, they cut any TLS connection to a known DNS server (1.1.1.1, 8.8.8.8, 9.9.9.9, etc.)

      When it breaks, it isn’t always obvious or easy to fix, but can cause problems for anything that has to talk to anything else. The biggest thorn it puts in my side is that short names [ThisPC] are served differently than fqdn [ThisPC.MyDomain.com]. Does NotMyApp use short or FQDN to resolve other machines? I don’t find out until the Wireshark.

          Really annoying is when recent devices don’t respect the DNS you’re advertising or allow configuration (Android…)

          My site is behind CGNAT on IPv4 with recently added fully routed IPv6. There are legacy control devices all over it that don’t speak IPv6, with local DNS records that allow them to be readily accessed while walking around with a mobile device… Allowed them to be accessed that is, until IPv6.

          The Android IPv6 stack ignores the RA for my local DNS and also resolves via v6 by default, forwarding local queries upstream and returning no results. Then it doesn’t bother to fall back to v4. Unrooted Android has no exposed configuration for IPv6 of any sort to modify its behaviour, no hosts file to override or any way I can see to fix this. I can’t even disable IPv6 on my phone.

          So to access my local devices from Android I need to use their full IPv4 address or VPN back into my own network… Oh wait, the stack is so broken that despite setting DNS in Wireguard, it still tries to resolve through upstream v6 first!

          Apparently recent smart TVs are doing similar even on IPv4, hard-coded to 1.1.1.1 or 8.8.8.8 to dodge ad blocking, which is plain malicious and ignores all standards…

          So anyways this is why DNS is dragon #3

          DNS setups can get fairly complicated with enterprise VPNs and stuff, but the main thing is probably just that DNS is built entirely around caching, so when something does go wrong or you’re trying to update something it’s easy for there to be a stale value somewhere. It’s also really fundamental, so when it breaks it can break anything.

          Overall, though, DNS isn’t terribly complex. It’s mostly just a key-value store with some caching. Running your own nameservers is pretty cool and will give you a much better understanding of how it all fits together and scales.

      CC BY-NC-SA 4.0

      This might be funnier than all those Facebook accounts with warnings about “I do not authorize anyone to use my photos!”

      Because they’re trying to copyright an internet comment that they posted on a service hosted by someone else, with a creative commons license attached. It’s like a step up in knowing how shit works, but still not knowing enough.

      If you really want ownership over what you say… don’t post it on the fucking internet.

        I mean, not really. You own the stuff you create regardless of who’s hosting it. Microsoft doesn’t own the copyright for the millions of projects hosted on GitHub either.

            I mean, probably not. That’s such a short post, chances are courts wouldn’t find it copyrightable. And obviously attaching a license at the end of your comments is useless in practice, because no one on the internet actually properly engages with copyright law. Plus suing over copy-pasting someone’s social media post is dumb as hell and no one does that, tho I do think you could technically do it and win, because current copyright laws make zero sense if you actually stop and think about it for any amount of time.

          You own the original, which you’ve written on your pc or phone. But the one that ends up on the website is a copy, on which you’ve granted the website owner a non-revokable license to do with as they please ie. a copy-right.

            Not really. You’ve granted the owner some rights, such as the right to host your content and present it to any user on the platform, but they don’t own it. Twitter can’t start using any art hosted on their platform for their branding, because it’s no theirs.

              They can if the license you granted them says they can. Read it. These platforms usually make you grant then extensive rights. Yes they don’t own the content but given such broad permissions it makes very little practical difference.

      The abysmal adoption of DNSSEC is just embarrassing, and I haven’t heard any good arguments for why we shouldn’t do it. There’s one blog post that gets passed around as justification for not adopting DNSSEC, but it doesn’t really go into any technical detail and is mostly just the author saying “I’m scared of governments and TLDs”… which is maybe fair, but you still have to trust them for regular CA certs and everything, so why not make thr base secure?

      Honestly, I might care slightly more about DNSSEC than IPv6 adoption… IPv4 exhaustion and NATing everywhere sucks, but the fact that you can’t trust DNS is like… insane.
