I have a very large list of domain names that I want to use python's socket.gethostbyname(hostname) to resolve the domain names to IPv4.

I do not want the loop to get stuck. do I need to set timeout? please note that when I tried socket.close() I got an error (see the post here).

The question is: do I need to set time out? is there any default time out?

What is the *real* problem you want to solve? *Why* to do you want to resolve so many domain-names? And when you say "very large list" how many are we talking about? Tens? Hundreds? Thousands? – Some programmer dude Jul 31 '18 at 15:01
At the moment 10s of thousands but can be more. It is for legitimate research purpose. – user9371654 Jul 31 '18 at 15:04
