Yes, that's right. The zoneversion response must match the "original QNAME" zone, meaning "the name actually sent in the Question section in the original query". Also note that the "TYPE" mentioned in this paragraph: > A name server MAY include more than one ZONEVERSION option in the > response if it supports multiple TYPEs. A name server MUST NOT include > more than one ZONEVERSION option for a given TYPE. is the *zoneversion* type. Not the QTYPE of the query. This is to allow the server to return more than one zoneversion "formats" in a single answer. > Might be worth adding that it MUST NOT return version info for any > records that don't match the original query.
