I am running 9.6.0-P1, and I added to my BIND options statement:

     avoid-v4-udp-ports { range 20030 20777;};

When I did an "rndc config" I saw this message:

     using default UDP/IPv4 port range: [1024, 65535]

in /var/adm/messages.  Is BIND doing what I wanted (e.g., use UDP
ports 1024-20029, 20778-65535), or is there some interaction with
the clause

     use-v4-udp-ports { port_list };

which I have not specified in the config file?  Thanks.
