joker.co.jp is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting joker.co.jp under watch moves it to the fast lane, where DomainDrift re-checks it about every 5 minutes and signs each reading, so a change becomes a dated event within minutes instead of waiting for the sweep to come round.
Watch joker.co.jp Watching a domain needs a DRM3 account. The reading above stays free and public either way.
Google (SPF sender)Steady. No change on record for joker.co.jp 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.

Subdomains (1)
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
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.
