7 Common DNS Transfer Mistakes and Security Risks to Avoid

Transferring DNS is a critical process for any website or business moving to a new hosting provider. While the process may seem straightforward, even small mistakes can result in downtime, email failures, or cyberattacks. Understanding DNS transfer security risks to avoid is essential to maintain a secure, functioning, and SEO-friendly website.

In this blog, we’ll explore seven common mistakes people make during DNS transfer and how to prevent them. Following these steps ensures a safe, seamless migration.


1. Not Backing Up DNS Records

Many website owners skip this crucial step. Losing your DNS configuration can result in broken websites, lost emails, and delayed troubleshooting.

How to Prevent:

  • Export all DNS records from your current provider before starting the transfer.

  • Keep a secure backup file stored locally or in a cloud repository.

  • Use this backup to restore settings if any misconfiguration occurs during the transfer.

Backing up DNS records is a simple yet powerful way to avoid major downtime.


2. Ignoring TTL Settings

TTL (Time To Live) determines how long DNS records are cached by servers. Ignoring TTL can lead to propagation delays, where some users see the old server while others access the new one.

How to Prevent:

  • Lower TTL values 48–72 hours before the transfer.

  • Monitor propagation to ensure updates reach all locations.

  • Revert TTL to normal values after the transfer is complete.

Adjusting TTL helps minimize downtime and provides a smoother user experience.


3. Overlooking MX Records

MX records control email routing. Failing to update them correctly during transfer can cause missed emails or bounces, disrupting business communications.

How to Prevent:

  • Backup existing MX records before the transfer.

  • Verify the records in the new DNS provider.

  • Send test emails to confirm proper routing.

Proper MX configuration ensures continuous email flow throughout the migration.


4. Weak Registrar Account Security

Unprotected registrar accounts make your domain vulnerable to hijacking. Attackers can gain access, redirect traffic, or steal the domain.

How to Prevent:

  • Use strong, unique passwords and enable two-factor authentication (2FA).

  • Keep registrar locks enabled during transfer.

  • Monitor account activity for unusual login attempts.

Strong security prevents unauthorized access and protects your online assets.


5. Ignoring DNSSEC

DNSSEC (Domain Name System Security Extensions) prevents attackers from tampering with your DNS records. Skipping DNSSEC implementation leaves your domain exposed to hijacking or cache poisoning.

How to Prevent:

  • Enable DNSSEC on both the old and new DNS providers.

  • Verify that all DNS records are signed correctly.

  • Regularly audit DNSSEC settings for compliance.

DNSSEC ensures cryptographic integrity and mitigates many common DNS threats.


6. No Monitoring After Transfer

Many website owners assume the transfer is complete once DNS records are updated. Failing to monitor the process can hide errors or security breaches.

How to Prevent:

  • Track propagation using tools like DNSChecker.org.

  • Verify website functionality and email delivery after migration.

  • Watch for unusual traffic patterns or security alerts.

Active monitoring ensures that any issues are detected and resolved quickly.


7. Rushing the Propagation Process

Switching too quickly without allowing sufficient propagation can result in inconsistent access, broken services, and frustrated users.

How to Prevent:

  • Wait for full propagation (24–48 hours) before considering the migration complete.

  • Test website and email services at multiple locations.

  • Communicate expected downtime or changes to users in advance.

Patience during propagation avoids disruptions and ensures a smooth transition.


Conclusion

Avoiding these seven common mistakes is crucial for a secure and successful DNS transfer. By backing up DNS records, adjusting TTL, securing registrar accounts, implementing DNSSEC, monitoring propagation, and testing thoroughly, you can reduce DNS transfer security risks to avoid and maintain uninterrupted service.

FAQs

Q1: What happens if I don’t back up DNS records?

If DNS records are lost during transfer, your website may go offline, emails can fail, and troubleshooting becomes time-consuming. Backups prevent these issues.

Q2: How long does DNS propagation take?

Propagation usually takes 24–48 hours, depending on TTL settings. During this period, some users may see the old server while others access the new one.

Q3: Can ignoring DNSSEC really affect security?

Yes. Without DNSSEC, attackers can tamper with DNS records, redirect traffic, or perform cache poisoning attacks.
