Overview

The response is a record: it carries the fields only a registration has.

Useful for the many registries that never say "registered" in so many words — they simply return the record, and the record's existence is the answer. Counting fields rather than looking for one is deliberate: a registrar name might appear in a preamble, but a registrar and a creation date and nameservers together are a registration.

THRESHOLD =

Three independent fields. Two is reachable by a chatty error notice; four loses the GDPR-redacted records that only keep domain, registrar and status.
