I heard good thing about using 184.108.40.206 in DNS server. Please see the article: https://blog.cloudflare.com/announcing-1111/
So I wanted to use it in SBS2011 DNS manager, but I run into an error when I plug it in.
In the past, I have not entered any DNS here in Forwarders tab so that it uses root hints.
Has anyone using 220.127.116.11 in forwarder tab in SBS2011?
Do you know why it is not accepting this IP address?
Should I add 18.104.22.168 in the Root Hints tab and move it to the top of the list?
