please add documentation about features dnssec ; production, recursiveness

[hanscees]

hi, I am looking for a dns proxy server.

I can find a lot of information on features. But I cannot find:

• do you recommend using the proxy in production environments
• do I need to use an upstream dns server, or is that optional in dns port 53 protocol. Can the server be used as a recursive dns?
• does the proxy verify dnssec or not, is that configurable?
• how does traffic scale compared to other dns proxy servers?

thanks.
