  • 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.


  • 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.
