How to Retrieve DNS Records in Python?

Estimated read time 2 min read

To retrieve DNS records in Python, you can use the dnspython library, which provides a convenient way to interact with DNS servers. Here’s an example of how you can retrieve DNS records using dnspython:

  1. First, install the dnspython library if you haven’t already done so. You can install it using pip with the command: pip install dnspython.
  2. Import the necessary modules:
import dns.resolver
  1. Use the dns.resolver.query() method to retrieve DNS records:
# Define the domain name you want to retrieve DNS records for
domain = "example.com"  # Replace with the desired domain name

# Retrieve DNS records
try:
    answers = dns.resolver.query(domain)
    for answer in answers:
        print(answer)
except dns.resolver.NXDOMAIN:
    print("No DNS records found for the domain.")
except dns.resolver.Timeout:
    print("DNS query timed out.")
except dns.resolver.NoNameservers:
    print("No nameservers found for the domain.")
except dns.exception.DNSException as e:
    print("DNS error:", str(e))

In this example, we use the dns.resolver.query() method to query the DNS records for the specified domain name. The query() method returns a dns.resolver.Answer object containing the DNS records.

We iterate over the answers object and print each DNS record. You can access specific attributes of the DNS records, such as the name, type, and data, according to your requirements.

We handle several exceptions that may occur during the DNS query process. For example, if the domain does not exist (dns.resolver.NXDOMAIN), a timeout occurs (dns.resolver.Timeout), no nameservers are found (dns.resolver.NoNameservers), or any other DNS-related exception occurs (dns.exception.DNSException), we print an appropriate error message.

Remember to replace 'example.com' with the actual domain name for which you want to retrieve DNS records.

Please note that DNS resolution may involve network requests and can be subject to network connectivity and configuration limitations. Ensure that you have a reliable network connection and that the DNS server you are querying is accessible.
