Perhaps I was unclear by my meaning.
A station running Ethernet II that receives a ethernet_Snap frame discards
it. It is unintelligible.
This is was what I meant by being in separate broadcast domains. A router
or server advertising services to more than one frame type has to generate a
separate advertisement broadcast for every frame type, thusly It is
reasonable to say that each frame type creates a separate broadcast domain.
(Same wire, separate domains.)
The question is rather blurry though. If it truly is a separate broadcast
domains, then the NIC should discard the frame without generating an
interrupt. If it passes it to the o/s to discard, then I'm not sure what it
is?!
IMHO, fwiw

Yes, each frame type is associated with a different network number. They
are not different representations of the same network number. They are
different networks.
Broadcast domains have nothing to do with it. If all devices in these four
networks are connected via hubs or switches, they see each other's
broadcasts. They process the broadcasts at the data-link-layer and only
process them further if they are running the same Ethernet frame type.
If these are really internal network numbers, then the question is moot.
Internal network numbers don't need a frame type!?
