By default, Dynamic Update clients will use the contents of the SOA
record (the MNAME field) and the NS records for a zone, to determine
where to send their Dynamic Updates. So as long as you have correct
information in those records, the Dynamic Updates for hello.com should go
to the master for hello.com, the Dynamic Updates for the
dynamic.hello.com zone should go to the master for that zone, and so
