Python's FTP library connects to an IP but not its domain


I’m using ftplib’s FTP class to connect to Using the domain doesn’t work, but using FileZilla I can see the IP address the domain name resolves to, and the IP address works.

def main():
print("Grabbing data...")
with FTP() as ftp:
    ftp.connect('', 21)

Specifically, the domain throws a GAIError ([Errno 11001] getaddrinfo failed). I’m using Python 3.8. How can I resolve the domain to its IP before passing it to the FTP class?

>Solution :

ftplib docs suggest to use address without leading ftp:// I did

from ftplib import FTP
ftp = FTP()

and output was
