RFC 2308, "Negative Caching of DNS Queries (DNS NCACHE)", March 1998Source of RFC: dnsind (int)
Errata ID: 4983
Publication Format(s) : TEXT
Reported By: Stéphane Bortzmeyer

Section 1 says:
"QNAME" - the name in the query section of an answer, or where this resolves to a CNAME, or CNAME chain, the data field of the last CNAME.
It should say:
"QNAME" - the name in the query section (RFC 1034, section 3.7.1).
RFC 2308 is the only RFC that defines QNAME this way. Original definition in RFC 1034 is clear, and is used by all other RFC since. (This point was raised during the development of RFC 8020, and is now discussed in the context of draft-ietf-dnsop-terminology-bis)
