We measure dead domains
so you don't buy a corpse.
h4xdomains grew out of a private research pipeline: a drop-catcher and screening system built to find aged .uk names worth keeping. The public site is a read-only window onto that database — the same numbers we use to decide what to catch.
What makes the data different: every name is checked against the registry directly, metrics come from four independent providers, and anything with a spam signature is flagged rather than quietly dropped.
How a domain gets into the database
Five stages. A name that fails any of them is kept, flagged and never recommended.
Nominet's daily list is pulled raw and stored before anything touches it.
Direct whois on every name — created, expiry, EPP status, registrar tag.
Ahrefs DR, Majestic TF/CF and referring domains, Moz DA. Four providers, no blending.
Every archive.org capture year, plus a stored homepage screenshot per year.
Backlinks, archived content and anchors checked against known patterns and flagged.
