How can I lookup hostname using the IP address with a timeout in Python?

0 votes
Hi all!

My question is - How could I search for a hostname considering that I already have an IP address corresponding to that machine?

To elaborate, is it possible to specify a custom timeout in a case where no reverse DNS entry is present?

I am actually going about doing this because I want to keep the code efficient and fast. I am confused as to what I am missing or if there is a better way to go about doing this?

All help appreciated!

Good question. I actually was stuck with something like this in the past.

Here's the solution. Check out the following piece of code:

>>> import socket
>>> socket.gethostbyaddr("")
('', [''], [''])

You can also implement the timeout on the particular function as you desire.

Hope this helped!
