Question about BIND and RPZ

Well I was working on the same but you really need to have good RPZ feeds.
I subscribed to third party feeds and have worked on my RPZ but later you
need to have good reporting engine. Hence better to have a dedicated RPZ
server instead and that's what I could suggest.

This is not marketing talk but I know vendor that I am working with who is
offering a good product instead.

Best Regards,
