How can I handle DNS errors in Python?

You can use the socket library to handle DNS errors. Specifically, you can catch exceptions like socket.gaierror.

Can you show me a code example?

Sure! Here's a simple example:

import socket
try:
    ip = socket.gethostbyname('nonexistent.domain')
except socket.gaierror:
    print('DNS lookup failed!')

What other exceptions should I be aware of?

In addition to socket.gaierror, you should also consider handling socket.timeout for timeout errors.

Is there a way to retry the DNS lookup?

Yes, you can implement a retry mechanism using a loop and a counter to limit the number of attempts.
