How to fill in domain name resolution TTL?

To fill in the domain name resolution TTL (Time to Live), you typically follow these steps:

1. Access DNS Management: Log in to your domain registrar or DNS hosting provider's control panel.

2. Select the Domain: Choose the domain for which you want to set or modify the TTL.

3. Edit DNS Records: Locate the DNS records you want to adjust. This could be A records, CNAME records, MX records, etc.

4. Set the TTL: For each record, there will be a field labeled TTL. Enter the desired time in seconds. Common TTL values include:

   • Auto: The DNS provider sets a default TTL.
   • 1 minute (60): Useful for temporary changes.
   • 5 minutes (300): Good for frequent updates.
   • 1 hour (3600): Suitable for most standard configurations.
   • 1 day (86400): Ideal for long-term stability.

5. Save Changes: After setting the TTL, save your changes. The new TTL will take effect after the current TTL period expires.

Example: If you want to set the TTL for an A record to 1 hour, you would enter 3600 in the TTL field for that specific record.

Recommendation: If you're managing DNS for a cloud-based application, consider using services like Tencent Cloud's DNSPod, which offers advanced DNS management features and flexible TTL settings to ensure your domain name resolution is both efficient and reliable.
