"Parent default" or something like that. There's no claim that it is
or isn't in the same organization, just that it's a parent name of the
target name.
For Scott's _dmarc.BANK. thing it would deliberately*not* be the same
organization.
Where is such generality discussed in DMARC? I don't recall seeing it.
That's draft-ietf-dmarc-psd
DMARC has had a consistent construct, which is 'the domain name that is at
the top of the organization's administrative hierarchy". Hence,
Organizational Domain. Nothing in the term requires that it be up the
'current' domain name chain.
I think a lot of people would be quite surprised to hear that the Org
domain might not be a parent of the original domain. I sure would.
I realize you could fake it with CNAMEs but that's different.
