I'm hoping I can get some behavior questions clarified regarding how PowerDNS 
recursor handles EDNS client-subnet requests/responses.  We're looking at 
sending ECS to Akamai, and they have very specific requirements for how the 
resolver behaves.

First, if the client sends a request to pdns-recursor that includes ECS data, 
they want to be assured that the client subnet sent to Akamai's authoritative 
server is the actual client IP/subnet as seen by pdns and not the IP/subnet 
from the client's ECS data.  I think that "use-incoming-edns-subnet" defaulting 
to "no" covers this case, but wanted to verify that having dnsdist in front of 
pdns-recursor, using the proxy protocol to pass requests, did not cause 
pdns-recursor to honor the forwarded ECS data.

The second question is regarding how the response is formulated.  Akamai wants 
to be assured that the scope and mask in Akamai's response is not passed back 
to the end user.  I did not see a clear answer one way or the other in the pdns 
documentation, so I wanted to verify that this is what pdns-recursor does.

If there are specific options to pdns-recursor and/or dnsdist that are needed 
to achieve this behavior, that would be appreciated as well.

Thanks,
Mark
