DomainDrift asked this domain for one hostname that nobody ever registered, and it answered. A domain that answers invented hostnames is running wildcard DNS. It is common and usually deliberate. A SaaS platform gives every customer a subdomain this way. How the check works

The proof

Signed at scan time. Check the math yourself. Every line above is part of one signed observation. Re-hash it and check the Ed25519 signature in your own browser; the only network request the check makes is for the published public keys.
