"BIND 9.9.4 provides support for Response Rate Limiting (RRL).  However it 
is not enabled by default when building BIND.  The reason for this is that 
BIND 9.9 is an Extended Support Version of BIND and per our policy on 
mangement of ESVs, we do not introduce any new features or functionality 
to a stable ESV version."
