I agree with others that spf3 should have "A" for a,ip4,ip6 and
distinguish by syntax. There are far too many errors of this sort.
I agree with Frank that this would be inadvisable and unnecessary.
Still, should it continue to be considered, please don't propose 'A'
as the name of the mechanism. More appropriate would be 'N' as in
'Name'.
Reason: Many APIs forgive, or even invite, a call to gethostbyname()
that passes a string representation of an IP4/6 address, echoing that
address instead of looking it up as an (invalid) FQDN. On the other
hand -- assuming 'A' was meant to stand for a general type 'Address'
-- I don't know of any that will take a string hostname into an
(overloaded?) gethostbyaddr(). So 'N' is closer to real-world
generalization. My take, at least.
