Fix Common DNS Record Issues in Squarespace
Learn to fix DNS record problems in Squarespace without the headache.
TL;DR: Key Points
- Replace placeholder values in Host and Data fields to save records
- Never use conflicting Host values for CNAMEs and other records
- Check Data field format to avoid errors like "Invalid IP address"
- Split DNS records if they exceed 255 characters
- Custom records in AAAA need fully expanded IPv6 addresses
Understanding and Resolving DNS Record Errors
DNS record issues in Squarespace usually come down to formatting problems or breaking the platform's specific rules. Here are the most common problems and how to fix them.
Replace Placeholder Values
Step-by-Step:
- Replace the example data in both Host and Data fields with your actual values. Those placeholders are just showing you the format.
- In the Host field, if you enter "mail", Squarespace automatically assumes "mail.yourdomain.com" even though you won't see the full domain displayed.
Avoiding Host Conflicts
Watch out for these scenarios:
- You can't add a CNAME record with "@" as the host value
- Using the same Host value for different record types (like CNAME and TXT) creates conflicts. If you see "This host is already in use", change the host value to something unique
Proper Formatting in Data Fields
If you're getting "invalid IP address" or hostname errors, check your Data field:
- Make sure the format is correct and doesn't end with unnecessary punctuation like periods
- For AAAA records, use the fully expanded IPv6 address format to avoid "Not a valid IPv6 address" errors
Managing Long DNS Records
For TXT or DMARC records over 255 characters:
- Use a third-party DNS record splitter or manually break the record into smaller chunks
- Double-check you're entering the divided segments correctly in your DNS settings
Watch for extra characters and typos (especially periods at the end of strings) that can break your DNS settings.
Pixelhaze Tip: Always double-check manually split records for accuracy before saving. One typo can break everything.
FAQs
Can I modify the Priority field for all DNS records?
Only for custom MX or SRV records. It's locked for other record types.
How do I fix conflicts in Squarespace's DNS settings?
Find and edit or delete any records that conflict with your new entry. This usually fixes save errors.
What if my TXT or DMARC records are too long?
Use a DNS record splitter to break TXT or DMARC records over 255 characters into manageable chunks.
Jargon Buster
- DNS Records: Settings that direct internet traffic by connecting your domain names with email servers, websites, and other services
- MX Record: Points to the email servers that handle incoming email for your domain
- CNAME: An alias that points one domain to another domain, useful for managing subdomains
- TXT Record: Holds text information mainly used for verification (like confirming domain ownership)
- DMARC: A protocol that authenticates emails and reduces spoofing risk
Wrap-up
DNS records in Squarespace can be tricky, but most common issues boil down to formatting errors or conflicts. Pay attention to character limits, use the right format, and check for conflicts before saving. Take a methodical approach and you'll keep your domain running smoothly.
