The same web page as all my DNS query services for domain reputation data points:


The S for httpS isn't required but will be forced anyway. That site is accessible to the public though to go further than seeing a
screenshot of the dashboard requires some level of identification or spoofing of identification. I don't say a whole lot about
RPZone.us in the description of it because I'm still shy of miscreants. Plus it seems that users don't know or want to know about
the role of authoritative name servers in my determination of domain reputation anyway.

I don't think you'll approve of my implementation at all - yet it has been found useful for production users.

I would have liked to respond to your question of whether more zones causes rpz enabled bind to slow down more but I eventually
realized I don't have the kind of query volume that would show any change in performance.

Thank you,
