AFAIK there's pretty much no such thing as authoritive unless you mean
being a primary nameserver. WHen you do an DNS lookup and you get a
'Non-authorative' answer it merely means that thet request has come out
of the nameservers cache after a previous lookup and it's htre for
non-authorative i.e. "I'm 99% sure this address is right, but it's not
100% because it came out of my cache and it might have changed in the
interim"
If you want to test this theory, do two lookups in a row for some
obscure domain name. You'll get two ansers, the second coming out of the
cache.
[root@graeme bin]# nslookup www.ucdavis.edu
Server: gateway.home
Address: 192.168.0.254
Name: www.ucdavis.edu
Address: 169.237.105.90
[root@graeme bin]# nslookup www.ucdavis.edu
Server: gateway.home
Address: 192.168.0.254
Non-authoritative answer:
Name: www.ucdavis.edu
Address: 169.237.105.90
Hope this helps.
