I'm not aware of any way to look up ACLs dynamically. However, a
configuration that involves reconfiguring BIND several times a minute
seems like a bad design. Can't you have pre-defined address ranges of
public or private zones, and just pre-configure these in BIND once?

Sometimes it helps to rethink your design.
