How to Use Reverse DNS Lookup Results
- Verify the domain matches the expected server (e.g., google.com for 8.8.8.8).
- Check for discrepancies indicating potential spoofing or misconfiguration.
- Use results to troubleshoot email delivery or network connectivity issues.
- Ensure PTR records are correctly set for your servers to avoid being flagged as spam.
