Wondering why we get variable results from the following command: dig
eftc.thehartford.com
(sometimes we get authority section and additional section feedback ...
sometimes we don't)
Usually we see the following:
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> eftc.thehartford.com
;; global options: printcmd
;; Got answer:

But occasionally we see :

I assume this is due to differences in response from different auth
nameservers. If that's the case ... what does one have set up to return the 2nd
response?
Thanks!
