Common DNS Record Troubleshooting Guide

Can't save a DNS record? Here are the main fixes for common DNS record issues:

Replace Placeholder Values

• Remove gray placeholder text in Host and Data fields
• Enter your actual values instead of example text
• Priority field is optional

Host Field Format Guidelines

• Domain name automatically appends after Host value
• Use @ if provider requests bare domain (yourdomain.com)
• Avoid duplicate Host fields across different record types

Invalid IP or Host Name Errors

• Verify Data field format is correct
• Remove trailing periods
• Double-check for typos

Conflicting Records Resolution

1. Open domains dashboard
2. Select domain name
3. Navigate to DNS Settings
4. Review Custom Records
5. Delete conflicting records
6. Add new record
7. Save changes

Priority Field Issues

• Only editable for MX and SRV records
• Field appears but remains locked for other record types

AAAA Record Troubleshooting

• Use fully expanded IPv6 addresses
• Example:
  • Incorrect: 2620:12a:8000::3
  • Correct: 2620:12a:8000:0:0:0:0:3

Long TXT/DMARC Records

• 255 character limit per record
• Split longer records into multiple strings
• Use DNS record splitter tools for automatic splitting
• Add each string separately to DNS settings

Important Notes:

• DNS changes take 24-72 hours to propagate
• Review existing records before adding new ones
• Contact your service provider for specific DNS requirements
• Always backup DNS settings before making changes
