this all seems terribly and unnecessarily convoluted.  the 6 arpa zones 
for this address space should simply be delegated to your nameservers. 
you are saying that your provider will not do this?

they appear to be attempting classless arpa delegation, but with net 
blocks larger than /24.  this seems odd to me.

they want you to have a zone named "", yet you 
have instead proclaimed a zone named "".  why they 
want this, though, is a mystery to me.

i'm not sure what they're/you're referring to with forwarders here, but 
it's not really relevant given the context so far.
