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'])

This is not what I am looking for. How can I do this operaton using scapy in python?

You should still be able to import the socket module and use socket.gethostbyaddr while in Scapy.

I also doesn't work very well for my case. I generally get the answer 'unknown host'

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')))
