I suggest getting some DNS bins online to track your requests. In this case I used requestbin.net
Here is an example that works

>>> ans = sr1(IP(dst="8.8.8.8")/UDP(sport=RandShort(), dport=53)/DNS(rd=1,qd=DNSQR(qname="7a645c14a2eaac.d.requestbin.net",qtype="A")))
Begin emission:
Finished to send 1 packets.
*
Received 1 packets, got 1 answers, remaining 0 packets
>>> **ans.an.rdata**
'127.0.0.1'
