When you encounter the domain name resolution status indicating "Domain name DNS has not been modified," it typically means that the changes you made to your domain's DNS settings have not yet propagated across the internet. DNS propagation can take anywhere from a few minutes to 48 hours, depending on several factors including the TTL (Time to Live) settings of your DNS records.
Here’s how you can address this issue:
Wait for Propagation: The most common solution is to wait. DNS changes need time to propagate worldwide. You can check the status using online DNS propagation checkers.
Verify DNS Settings: Ensure that the DNS settings you entered are correct. Double-check the IP addresses or CNAME records you have specified.
Reduce TTL: If you need the changes to propagate faster, you can reduce the TTL of your DNS records before making changes. For example, changing the TTL from 24 hours to 5 minutes can speed up propagation. However, this should be done in advance of making changes, as it takes time for the reduced TTL to take effect.
Clear DNS Cache: Sometimes, your local DNS cache might be causing the issue. You can clear your DNS cache by running specific commands in your operating system. For Windows, you can use ipconfig /flushdns, and for macOS, you can use sudo killall -HUP mDNSResponder.
Contact Registrar: If the issue persists, contact your domain registrar’s support team. They can verify if there are any issues on their end or if they can force a DNS update.
Use Cloud Services for DNS Management: For more efficient DNS management, especially in cloud environments, consider using services like Tencent Cloud’s DNSPod. This service offers advanced DNS management features, including high-speed DNS resolution, security protection, and easy integration with other cloud services.
By following these steps, you should be able to resolve the "Domain name DNS has not been modified" issue effectively.
