Inverse DNS with Multiple DNS servers

So, just so I understand... a netblock (Class C for example) can only
have one server provide reverse-mapping (if the whole block is
contiguous).  But, if you subnet that baby four times (.192), you could
ask the upstream ISP to delegate four different zones, each to a
different DNS server on each of the four subnets?
