There's always going to be at least one record, be it an NS for 
delegation or CNAME for 2317, for each IP that's not being delegated at 
a higher dot boundary.  It's a question of what other records are needed 
to support it.  (This on the upstream ISP's side.)

Then there's the question of what needs to be done on downstream side. 
This is highly dependent on what technique you use.

There's the cross delegation hack, but that's considerably more work for 
a few IPs.
