10.1.1. CNAME terminology
It has been traditional to refer to the label of a CNAME record as
CNAME". This is unfortunate, as "CNAME" is an abbreviation of
"canonical name", and the label of a CNAME record is most certainly
not a canonical name. It is, however, an entrenched usage. Care
must therefore be taken to be very clear whether the label, or the
value (the canonical name) of a CNAME resource record is intended.
In this document, the label of a CNAME resource record will always
referred to as an alias.
