The Proxy Protocol is currently not supported by PowerDNS Authoritative
Server so it's just dropping the packets sent by dnsdist.
I'd suggest having a look at EDNS Client Subnet instead:



Enabling EDNS Client Subnet will make the original client IP available
to your backend, which might be enough depending on how you log queries.
