Hi Shawn,  

The resursive support for EDNS client-subnet is only in our subscription 
edition.  It is not in any version of 9.11.0. The subscription edition is 
available to support subscribers but is not posted publicly.  The company that 
sponsored the work required that we embargo it from the open source to give 
them a chance to market it in their own version of BIND.  If you have any more 
questions about this, I invite you to unicast to me at vi...@isc.org.

Regards,

Vicky Risk
