Is there any way to do a reverse lookup using python, to check the list of websites sharing the same IP address in a shared hosting?

Technically, you can use DNSPython to do a reverse lookup.
Pip install it
$ pip install dnspython Then do your reverse query:
>>> from dns import resolver >>> from dns import reversename >>> addr = reversename.from_address("74.125.227.114") >>> resolver.resolve(addr, "PTR")[0] <DNS IN PTR rdata: dfw06s16-in-f18.1e100.net.> socket.gethostbyaddrYou can also use socket.gethostbyaddr
>>> import socket >>> name, alias, addresslist = socket.gethostbyaddr('192.30.252.130') >>> name 'ip1c-lb3-prd.iad.github.com' Note that you'll want to check for a socket.herror Exception when using gethostbyaddr.
As for finding out what sites are hosted on a particular IP, this may not lend the best results in a shared hosting environment. It will likely tell you about the provider, not the site:
14:38:43 ~/code/tmp$ ping mozeyondown.com PING mozeyondown.com (173.203.99.161): 56 data bytes 64 bytes from 173.203.99.161: icmp_seq=0 ttl=56 time=40.924 ms Let's look up that address now
14:38:54 ~/code/tmp$ dig +noall +answer -x 173.203.99.161 161.99.203.173.in-addr.arpa. 86053 IN PTR 173-203-99-161.static.cloud-ips.com. Looking it up via Python
>>> import socket >>> name, alias, addresslist = socket.gethostbyaddr('173.203.99.161') >>> name '173-203-99-161.static.cloud-ips.com' Same goes for using DNSPython.
google.comA record points to74.125.228.97, but the reverse DNS entry for that IP isiad23s08-in-f1.1e100.net.
