I think you just hit the mail on the head with my ISP is blocking DNS 
traffic that’s not going to their servers.

when I issue  drill facebook.com  I get rcode NOERROR, but
drill facebook.com @8.8.8.8
I receive error msg  Error: error sending query: Error creating socket
I believe 8.8.8.8 is one of googles main dns services. I also tried 
using the dns ip for at&t and got same results.

Now we both know that things are changing on the public internet to 
address dos attacks. This is a transparent solution to many people but 
comes to light with built-in "root zone" function of unbound. This 
should be brought to the attention of the unbound maintainers so they 
can remove the built-in "root zone" function from the source as it has 
become obsolete.

Thanks for you help and insight.
