DDNS - Question of best practices.

[Chris Buxton]

Dynamic updates must be processed by the primary master server (your  
new hidden master, in this case). However, it's possible to set the  
slaves to forward updates to the master, so that the DHCP server can  
send updates to the local slave.

So, to answer your question, either way will work.
