DNS records can experience various issues that may affect their functionality. Here's a comprehensive guide to troubleshooting common DNS record problems.

Record Not Saving Issues

When adding a record, ensure you:

  • Replace placeholder values in Host and Data fields with actual values
  • Format the Host field correctly:
    • For custom records, only enter the subdomain (e.g., "mail" instead of "mail.yourdomain.com")
    • Use "@" to represent the root domain
    • Avoid host conflicts with existing records

Invalid Data Format Errors

If you receive "Invalid IP address" or "Hostname error":

  • Check Data field formatting
  • Remove trailing periods
  • Ensure values match provider requirements

Conflicting Records Resolution

To resolve record conflicts:

  1. Open domain control panel
  2. Navigate to DNS Settings
  3. Review Custom Records
  4. Delete conflicting records
  5. Add new records
  6. Save changes

Note: Allow 24-72 hours for nameserver changes to propagate.

Priority Field Limitations

  • Priority can only be edited for MX or SRV records
  • Other record types will show an uneditable Priority field

AAAA Record Requirements

Use expanded IPv6 addresses:

  • Incorrect: 2620:12a:8000::3
  • Correct: 2620:12a:8000:0:0:0:0:3

Long TXT/DMARC Records

For records exceeding 255 characters:

  • Split into smaller segments
  • Add each segment separately
  • Use online DNS record splitting tools
  • Maintain proper formatting for each segment

Error Resolution Steps

For "Enter valid other address data" errors:

  1. Check record length (must be under 255 characters)
  2. Remove extra characters, especially trailing quotes
  3. Split lengthy records into segments
  4. Verify correct formatting

Remember that DNS changes typically take 24-72 hours to fully propagate across the internet. For specific technical issues with third-party services, contact their support directly.
