Almost every time anyone mentions DNSSEC here on HN, you pop up like a jack-in-the-box to claim that nobody is using it and that it is dead. And it’s always you, nobody else. Whereas, from where I sit, I work at a registry and DNS server host (among other things) where about 40% of all our domains have DNSSEC (and that number is constantly climbing). Every conference I go to, and in every webinar, people seemingly always talk about DNSSEC and how usage is increasing.

You might have some valid criticism about the cryptography; I would not be able to judge that (except when you are basing it on wildly outdated information). I’m not an expert on the details; you could most assuredly argue circles around me when it comes to the cryptography, and possibly about the DNSSEC protocol details as well. But, from my perspective, your continuous claim that “nobody uses” DNSSEC is simply false. DNSSEC works, usage of DNSSEC is steadily increasing, and new protocols (like DANE) are starting to make use of DNSSEC for its features. Conversely, I only relatively rarely hear anything about MTA-STS.

Take any list of the top domains on the Internet --- any of them at all --- and run them through a trivial script, like:

    #!/bin/sh
    while read domain
    do
    ds=$(dig ds $domain +short)
    echo "$domain $ds"
    done

... and note that virtually none of the domains, in any sane list of top domains, are signed. That was true several years ago and remains true today, despite the supposed "increase in usage" of DNSSEC.

What's actually changed is that registrars, especially in Europe, now apparently auto-sign domain names. That creates a constant stream of new, more-or-less ephemeral signed zones that gives the appearance of increasing DNSSEC adoption. Of course, this is also security theater (the owners of the zones don't own their keys!). The real figure of merit for DNSSEC adoption is adoption by sites of significance, and that has been static, and practically nonexistent, for a decade.

It is no surprise to me that people working on the DNS talk quite a bit about DNSSEC. People who worked on SNMP talked quite a bit about SNMPv3, and IPSEC people probably really believed there would be Internet-wide IKE. None of those things happened, because what matters in the real world is what the market decides. Most especially at the companies with serious security teams, DNSSEC is a dead letter standard.

Registrars can’t “auto-sign” domains. Only DNS server operators can do that, if they have the cooperation of the registrar. And the DNS server operators is the only workable definition of “owners of the zones”, so they do own their keys. It can’t work any other way.

In fact, the new CDS and CDNSKEY DNS records allow it to work the other way around; DNS server operators can auto-sign domains, and the registrars need not be involved at all.

People said the same about IPv6. Or maybe you do, too?

> People who worked on SNMP talked quite a bit about SNMPv3

I seem to recall you mentioning quite often how WHOIS was dead and would be replaced by RDAP. That didn’t happen either.

> IPSEC people probably really believed there would be Internet-wide IKE

Interestingly, that problem could in theory be solved by DNSSEC. We’ll see what happens.

I don't think you ever saw me mention that WHOIS is dead, not least because that's not a thing I believe. What a random thing to say; you can just use the search bar to immediately see the (very few) things I've had to say about RDAP here.
