I wanted to understand how Order and Preference Values have an impact on the
answers Received from the DNS Server
I am asking because, I have 4 records for NAPTR Query, as below
carrier1.com 86400 IN NAPTR 50 50 “s” “SIPS+D2T” ““
“_sips._tcp.carrier1.com.”
carrier1.com 86400 IN NAPTR 90 50 “s” “SIP+D2T” ““
“_sip._tcp.carrier1.com.”
carrier1.com 86400 IN NAPTR 100 100 “s” “SIP+D2U” ““
“_sip._udp.carrier1.com.”
carrier1.com 86400 IN NAPTR 120 100 “s” “SIPS+D2U” ““
“_sip._tcp.carrier1.com.”
I am expecting to receive the answer as _sip._udp.carrier1.com but i receive
_sip._tcp.carrier1.com
How could I change this?
