Controls statement BIND 9.10.0b2 CentOS6.5

[David Forrest]

With no controls statement,  I get the following error (annoying - not fatal):

Mar 20 11:56:01 maplepark named[26046]: starting BIND 9.10.0b2 -u named

Mar 20 11:56:01 maplepark named[26046]: command channel listening on ::1#953

But I can't seem to construct a controls statement to only listen to the 
IPv6 loopback.  As it just retries on a failure to IPv4 it works anyway 
but it is annoying to get the error message on startup.  I don't have 
either address in the /etc/rndc.key file, just the key.
