in the output from nslookup.

rather than by consulting an authoritative source such as an authoritative server
or secondary server
- authoritative server: A primary or secondary server for a zone is called an authoritative server when it obtains its information directly
from data files describing the zone .
- secondary server: In addition to its primary server, a zone may have one or more secondary servers. A secondary server provides an
alternative source for information on the zone.
