To remediate the misconfiguration of AWS Registered Domains having no hosted zones, you can follow these step-by-step instructions using the AWS CLI:

1. Install and configure the AWS CLI: Ensure that you have the AWS CLI installed on your local machine and configured with the appropriate AWS credentials. You can refer to the AWS CLI documentation for installation and configuration steps.

2. List the registered domains: Run the following command to list all the registered domains in your AWS account:

   aws route53domains list-domains
   

3. Create a hosted zone: For each registered domain that does not have a hosted zone, create a new hosted zone using the following command:

   aws route53 create-hosted-zone --name <domain-name> --caller-reference <unique-reference>
   

   Replace <domain-name> with the registered domain name for which you want to create a hosted zone. Provide a <unique-reference> to identify the hosted zone creation request.

4. Update the domain’s nameservers: After creating the hosted zone, you need to update the nameservers of the registered domain to point to the newly created hosted zone. Retrieve the nameservers for the hosted zone using the following command:

   aws route53 get-hosted-zone --id <hosted-zone-id> --query 'DelegationSet.NameServers'
   

   Replace <hosted-zone-id> with the ID of the newly created hosted zone.

5. Go to the domain registrar: Access the website of the domain registrar where you registered the domain.

6. Update the nameservers: In the domain registrar’s management console, locate the DNS settings or nameserver configuration for the registered domain. Replace the existing nameservers with the ones obtained from the previous step.

7. Verify the configuration: Wait for the DNS changes to propagate, which usually takes some time. You can use tools like dig or online DNS lookup tools to verify that the domain’s nameservers are updated correctly and pointing to the newly created hosted zone.

8. Repeat for other registered domains: Repeat steps 3-7 for each registered domain that does not have a hosted zone.

By following these steps, you can remediate the misconfiguration of AWS Registered Domains having no hosted zones using the AWS CLI.

To remediate the misconfiguration “AWS Registered Domains Has No Hosted Zones” in AWS Route53 using Python, follow these steps:

1. Install the required dependencies:

   • Install the AWS SDK for Python (Boto3) using the command: pip install boto3

2. Import the necessary libraries in your Python script:

import boto3

3. Create a session using your AWS credentials:

session = boto3.Session(
    aws_access_key_id='YOUR_ACCESS_KEY',
    aws_secret_access_key='YOUR_SECRET_ACCESS_KEY',
    region_name='YOUR_REGION'
)

Replace YOUR_ACCESS_KEY, YOUR_SECRET_ACCESS_KEY, and YOUR_REGION with your actual AWS credentials and desired region.

4. Initialize the Route53 client using the session:

route53_client = session.client('route53')

5. Retrieve the list of registered domains:

response = route53_client.list_domains()
registered_domains = response['Domains']

6. For each registered domain, check if it has any associated hosted zones:

for domain in registered_domains:
    response = route53_client.list_hosted_zones_by_name(DNSName=domain['DomainName'])
    hosted_zones = response['HostedZones']
    
    if len(hosted_zones) == 0:
        print(f"Domain '{domain['DomainName']}' has no hosted zones.")
        # Perform the necessary remediation steps here

7. Perform the necessary remediation steps for the domains with no hosted zones. This can vary depending on your requirements. For example, you can create a new hosted zone for the domain using the following code:

response = route53_client.create_hosted_zone(
    Name=domain['DomainName'],
    CallerReference='YOUR_UNIQUE_CALLER_REFERENCE'
)

Replace 'YOUR_UNIQUE_CALLER_REFERENCE' with a unique string to identify the hosted zone creation request.

8. Optionally, you can add additional logic to handle errors, logging, and any other required operations.

By following these steps, you can use Python and the AWS SDK (Boto3) to remediate the misconfiguration of “AWS Registered Domains Has No Hosted Zones” in AWS Route53.
