Configure Root Domain Records

This check ensures that the root domain is correctly configured with both A (IPv4) and AAAA (IPv6) DNS records. Proper configuration ensures reliable connectivity for users accessing the website over IPv4 and IPv6 networks.

Check Details

  • Resource: Domain
  • Check: Configure Root Domain (A and AAAA records)
  • Risk: If A or AAAA records are missing or misconfigured, users may not be able to access the website via IPv4 or IPv6, leading to downtime or connectivity issues.

Remediation via Domain Registrar Console

  1. Log in to your domain registrar’s console.
  2. Open Domain Management for the affected domain.
  3. Navigate to DNS or DNS Settings.
  4. Ensure the root domain (example.com) has at least the following records:
    • An A record pointing to the server’s IPv4 address
    • An AAAA record pointing to the server’s IPv6 address (if supported)
  5. If records are missing, add new DNS records as shown below: 
    

Name/Host: @
Type: A
Value: 192.0.2.123
TTL: 3600

Name/Host: @
Type: AAAA
Value: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
TTL: 3600
  6. Save the changes.

Note: If IPv6 is not supported by the hosting provider, AAAA records may be omitted.

Verification

Verify that the A and AAAA records are visible using command-line tools. 


nslookup -type=A example.com
nslookup -type=AAAA example.com

or


dig A example.com
dig AAAA example.com

Replace example.com with your actual domain name.
