Question
How can I do reverse DNS lookup using scapy
in Python? I look for it in Google but I couldn't find related to this topic.
Solution 2
Ok. I have found my answerm and I want to share it in here, because someone could look for same thing. One line of code is enough to make a reverse dns query in scapy, which is:
sr1(IP(dst="8.8.8.8")/UDP()/DNS(rd=1,qd=DNSQR(qname="211.196.59.69.in-addr.arpa", qtype='PTR')))
OTHER TIPS
Reverse DNS is already written into Python's Socket module. Simply use the following:
>>> import socket
>>> socket.gethostbyaddr("69.59.196.211")
('stackoverflow.com', ['211.196.59.69.in-addr.arpa'], ['69.59.196.211'])
