Please note the meaning of the word SHOULD when read in an RFC
SHOULD This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
Please do not confuse it with the word MUST
MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification.
So there are occasions where the lookup of the A record is not required.
