DNSSEC: Protecting Your Traffic From Forgery
The hard part of DNSSEC was finished years ago. Counted from the live root zone on 27 September 2026, 1,351 of 1,438 top level domains carry a DS record and every one of the 1,038 gTLDs is signed. Then it stops dead. A census of every gov.uk domain in the official register finds 39 signed out of 2,390 that still resolve, nine of them parish councils, while HMRC, the NHS, GCHQ and the National Cyber Security Centre are not among them. One certificate authority in nine has signed. So has one Linux distribution in three. windowsupdate.com has no DS at all. This is what a forged answer actually costs, what signing does about it, why the usual excuses do not survive contact with the numbers, and whether forty-two years after Mockapetris the real problem is that almost nobody understands what DNS actually promises.
