If they are full C's delegatd as C's to you,

1. you can't re-delrgate as a C to him.  you can delegate a C /24 as two /25's.

2. you also have the option of him running a non-delegated (stealth) master 
for the C's reverse zone, and your DNS, delegated, slaves to his.   He 
enters the data into his machine, you serve the data to Internet.

For less-ClassC-subnet delegation, then follow RFC2317.
