[Pdns-users] EDNS and NAT

[Boden Garman]

Hi list,
We would like to send EDNS subnets so the various CDNs can respond with local caches for our users behind CGNAT. They're on the standard 100.60.0.0/10 range so `ecs-add-for` shouldn't pick them up. 

Reading the docs, I am wondering if `ecs-scope-zero-address` is the right setting to be adjusting. I am setting it to a public IP in the nat pool, and I can see it being sent with tcpdump but it's sending as a /32. Is this is the expected behavior with the default ecs-ipv4-bits of 24?

We're using PowerDNS 5.2.6 recursor 

Cheers
