Checking the RFC. To my reading the final stanza is not checked

So in this case AI got it right.
I don't follow. What's your "final stanza" referring to, and
what's wrong with the RFC in connection with it?
I should have used the term 'final qnum' but I think that would be obscure.
I meant the fourth number in the IPv4 dotted-quad notation.
As for the RFC? It's precise and definitive. My only concern is that
some mail system implementer may 'improve' the RFC and restrict the
acceptable address range to a /32 when they see a non zero final qnum in
a /24
