When the EHLO host name references IP addresses that match the

the DNS namespace is of very little help when it comes to conclusions about
"common administration". See, for example, RFC 5507, section 4:
DNS hierarchy neither follows nor implies administrative hierarchy.
Because of that, it cannot be assumed that data attached to a node in
the DNS tree is valid for the whole subtree. [...]
Since I'm sure you were already aware of this, I'm wondering in what way
I might have misread your statement.
