are configured in the Zone file
I have done 2 different Tests
I have configured following records in the Zone file e164enum.net with TTL
value as 0
2.7.5.2.7.9.2.5.3.1.8.e164enum.net. IN NAPTR 100 10 "u" "E2U+sip"
"!^.*$!sip:7895673...@atlanta.com;user=phone!" .
2.7.5.2.7.9.2.5.3.1.8.e164enum.net. IN NAPTR 100 10 "u" "E2U+sip"
"!^.*$!sip:7895673...@atlanta.com;user=phone!" .

Since I did not want the Answers to be toggled in each susbsequent digs, and I
wanted the Answers to be in the same Order they were configured in the Zone
file(since the Order and Preference of both these records were same), I enabled
this line in the options field of named.conf
rrset-order {order fixed;};
and restarted named
I ran the dig query again
This time, the Answers did not toggle, but I found that, the second configured
RR was being Answered as first always sip:7895673...@atlanta.com
Why is Bind answering the Second RR as first and not my original First RR as
1st Answer?
