Here why authority section is not returned? Actually authority section
should be returned with SOA right?
For CNAME answers, the authority for destination (.) is returned and
authority is returned if it's known and configured.
And here it is known to be NXDOMAIN when the server is recursive:
[...@maplepark ~]$ dig cname.td3497.com. any
