Steady. No change on record for coastal.edu in the last day; this reading matches the one before it. The steady record is signed like every other reading. Watch it to catch the next move the moment it lands.

SIGNED-OUT VIEW Provider names, posture and counts are shown. The record values - every DNS answer, each subdomain hostname, raw TXT, IPs, cert names and WHOIS - are the product. Sign in for the full signed record, or use the API with a key.

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.
