The Dead Web: 1.65 Billion Hostnames That No Longer Resolve
We compared the master DomainsProject corpus (3.12 billion unique hostnames ever observed) against the 17 April 2026 active crawl (1.47 billion currently resolving) and found that 52.9% of the observable web no longer answers the DNS. .com alone holds 808 million dead hostnames; the five Freenom-managed ccTLDs (.tk, .ml, .ga, .cf, .gq) are 99% extinct; the new-gTLD program churns at 75% dead; and a small spine of restrictive ccTLDs — .jp, .it, .de, .nl — sits below 30%.
