Specifically, the following part: Note that the answer section of an authoritative answer normally contains only authoritative data. However when the name sought is an alias (see section 10.1.1) only the record describing that alias is necessarily authoritative. Clients should assume that other records may have come from the server's cache. Where authoritative answers are required, the client should query again, using the canonical name associated with the alias. --- JINMEI, Tatuya Internet Systems Consortium, Inc.
