Hello all, 

First let me state that I am pretty new to DDNS and I am looking for a
best practice of implementing DDNS.

I have a pretty large network, and I am looking to enable DDNS at all
the schools as well as the central office of the Chicago Public School

The following scenario best describes my network right now. 

I have:

1 master DNS server 
3 slave DNS servers 

The schools use 2 of the the slaves and the central office use the
master and the other slave. Right now all the slaves are updated by the
single master.

My plan is to implement a HIDDEN master, which will update the other 4. 

This is where I am a little unsure.

Should the DHCP server update the hidden master via DDNS or should I
update the other 4 directly.
