Reverse Delegation Sanity check

[Michael Cunningham]

Folks,

I need a little sanity check on my work before I put this into
production since I havent done reverse delegation for a LONG time.

I have 2 subnets that need to be delegated out to another nameserver.

First is the 137.236.0.0/255 Class B address which my main nameserver is
responsible for. I need to delegate out 137.236.214.0/255 to another dns
server.

Second is the 205.183.255.0/255 Class C address which is another
nameserver I am responsible for. I need to delegate out a subnet
of that class C. 205.183.255.223/224 to another dns server.

First in the 137.236 nameserver I put in the db.137.236 file

255/0.214  NS  medns1.messagereach.com.
1.214 CNAME 1.214.255/0.214
2.214 CNAME 2.214.255/0.214
3.214 CNAME 3.214.255/0.214
4.214 CNAME 4.214.255/0.214
5.214 CNAME 5.214.255/0.214
6.214 CNAME 6.214.255/0.214
.. and so on up to 254 for the class C

Then on the medns1.messagereach.com server I setup in the named.boot file
(working on solaris 2.6) 

primary 255/0.214.236.137.in-addr.arpa db.137.236.214

For the Class C subnet delegation I do on the 205.183.255.0/255 primary
dns server I put in the db.205.183.255 file

224/223  NS   medns1.messagereach.com. 
224     CNAME 224.224/223  
225     CNAME 225.224/223  
226     CNAME 226.224/223  
227     CNAME 227.224/223  
228     CNAME 228.224/223  

.. And so on up to 255 for the subnetted class C.

Then on the medns1.messagereach.com server I setup in the named.boot file

primary 224/223.255.183.205.in-addr.arpa db.205.183.255.223

Is this correct? If not where did I go wrong? Any shortcuts I could use?
Thanks for any help..

Mike
