I don't belive that is correct. I think the fallback servers are for
when a connection to a name server fails. If it returns nxdomain, other
dns servers aren't supposed to be checked.

If you want local A records, then you need a local dns server that returns
information for locally defined domains and does something else (either
forward to another dns server or do iterative lookups using the root zone
hints) for nonlocal domains.
