How to find a host's FQDN from its IP address in Python

I am writing a python script in which I have an IP address from which I need to find the associated host's FQDN.

I know there are socket.getfqdn() and socket.gethostbyaddr() calls but they are giving only the hostname in this case and not the FQDN.

However, if I'm running 'host ' or 'nslookup ' on my local linux pc it shows me the FQDN of that host.

Please help me if there is any way to achieve it in Python.

Use dnspython.

Examples for reverse lookup include things like this:

>>> from dns import resolver,reversename
>>> addr=reversename.from_address("74.125.228.97")
>>> str(resolver.query(addr,"PTR")[0])
'iad23s08-in-f1.1e100.net.'
>>>
