How LDNS Looks This Up
LDNS queries are issued live against authoritative public sources at the moment you load the page. There is no caching of historical results — what you see is what was returned just now.
Server-side calls (where applicable) are proxied through Cloudflare with edge caching, but every cache entry is invalidated frequently so the picture stays current.
