DNS records won't save or work properly? Here's a comprehensive troubleshooting guide to help you resolve common DNS record issues.

Replace Placeholder Values

• When adding custom records, replace gray placeholder text in Host and Data fields
• Priority field is optional
• Use actual values instead of example data

Host Field Format Guidelines

• Your domain name automatically appends after Host values
• For mail.yourdomain.com, only enter "mail"
• Use @ in Host field when provider requests bare domain (yourdomain.com)
• Avoid duplicate Host fields across different record types

Common Error Messages and Solutions

Invalid IP Address or Host Name:

• Check Data field format
• Remove trailing periods
• Verify information accuracy

Conflicting Records:

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 or SRV records
• Not modifiable for other record types

AAAA Record Formatting

• 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 online DNS record splitter tools
• Add each string separately

Important Notes

• DNS changes take 24-72 hours to propagate
• Contact your service provider for specific DNS requirements
• Use the Squarespace Forum for peer support

Remember: DNS configuration requires precise formatting and patience during propagation. Always verify information from your service provider before making changes.
