Question 1

What are TXT records used for?

Accepted Answer

TXT records store text-based information in DNS and are used for domain verification, email authentication (SPF, DKIM, DMARC), site ownership verification for search engines and services, security policies, and various third-party service configurations. They're versatile and can contain almost any text-based data.

Question 2

How do I verify domain ownership with TXT records?

Accepted Answer

To verify domain ownership, add a specific TXT record provided by the service (like Google Search Console) to your domain's DNS. The service will then check for this unique text string to confirm you control the domain. This method is secure because only someone with DNS access can add the record.

Question 3

Can TXT records affect email delivery?

Accepted Answer

Yes, TXT records are crucial for email authentication and delivery. SPF records (in TXT format) specify authorized mail servers, DKIM records contain public keys for email signing, and DMARC records define email authentication policies. Properly configured email-related TXT records improve deliverability and prevent spoofing.

Question 4

What's the maximum length of a TXT record?

Accepted Answer

Individual TXT record strings are limited to 255 characters, but multiple strings can be concatenated for longer content. The total TXT record length can be up to 65,535 characters when using multiple strings. For very long content, consider breaking it into multiple TXT records or using alternative approaches.
