A couple points, Rod:

1. I believe bottom posting is preferred here.

2. Well, yeah, it’s easy to go “backwards” with DNS/IP addresses. You can do it from any command line interface. That’s not the point here with Cloudflare’s DNS, or other publicly available DNS services. When you default to your ISP’s DNS servers, it’s easy for them to tie DNS requests to a particular customer (you) and monetize (share, sell, etc.) that information. What I believe Cloudflare is saying with their DNS service is “Hey, we won’t do that.”
