bring clientip to the authoritative server

[Duan Duan]

Hey Guys,


I have a cache, which can cache the client's domain name request and forward the client ip to my bind authority service in the form of ecs to hit views.


But I know that after bind 9.13, authoritative ecs functionality is not supported.


So I've been unable to upgrade the bind version.


What else can I do to forward the client ip to my authoritative bind and hit view based on acl？


PPV2 seems to be a solution direction,  it can bring real client ip to authoritative bind server and hit views.


But PPV2 seems to be an experimental function as well?


Is there any other way? Can you give me a suggestion?


Kind regards
Duan
