TXT Lookup

Look up TXT DNS records for a hostname.

The TXT Lookup tool from Tool World provides a straightforward way to query and display the Text (TXT) DNS records associated with any specified hostname or domain. TXT records are incredibly versatile, primarily used for storing plain text information that external services can read. For instance, system administrators frequently use TXT records to publish Sender Policy Framework (SPF) records, which help prevent email spoofing by specifying which mail servers are authorized to send email on behalf of a domain. Without correct SPF records, legitimate emails might be flagged as spam.

Beyond email authentication, TXT records are crucial for implementing DomainKeys Identified Mail (DKIM) and Domain-based Message Authentication, Reporting, and Conformance (DMARC) policies, further enhancing email security and deliverability. Webmasters also leverage them for domain ownership verification processes required by services like Google Search Console or various cloud providers, proving they control a particular domain.

Using the TXT Lookup is simple: you input a hostname like "example.com" or a subdomain like "mail._domainkey.example.com", and the tool quickly returns all associated TXT records. The output typically includes the record's value, which might be a long string containing configuration details or verification codes. A key tip for users is to be precise with subdomains, as a missing underscore or incorrect prefix can lead to no records found, even if they exist for the correct entry. This tool makes it easy to diagnose setup issues or simply inspect a domain's published text information.

How to use TXT Lookup

  1. Access the Tool

    Navigate to the TXT Lookup page on Tool World. You'll find a dedicated input field for the hostname.

  2. Enter Hostname

    Type the domain name or specific hostname you wish to query into the provided input box. Ensure accuracy for subdomains like _dmarc.yourdomain.com.

  3. Initiate Lookup

    Click the "Lookup TXT Records" button to send your request to the DNS servers. The tool will process your query instantly.

  4. Review Results

    The TXT records associated with your entered hostname will be displayed in the output area. Each record will show its full text string.

  5. Analyze Data

    Examine the returned TXT records to verify SPF, DKIM, DMARC configurations, or any other specific text information you are looking for.

Frequently Asked Questions

What information do TXT records typically contain?

TXT records commonly hold information for email authentication (like SPF, DKIM, DMARC policies), domain verification codes for services like Google, or general administrative notes.

Why would my TXT Lookup return no records?

This could happen if the domain or hostname you entered does not have any TXT records published, or if there's a typo in the hostname, especially with specific prefixes for services like _dmarc or mail._domainkey.

Can I look up TXT records for a subdomain?

Yes, the TXT Lookup tool fully supports querying TXT records for subdomains. Simply enter the full subdomain, for example, blog.example.com or _dmarc.example.com.

How is a TXT record different from a CNAME or A record?

A TXT record stores arbitrary text data for various purposes, while an A record maps a domain name to an IPv4 address, and a CNAME record creates an alias from one domain name to another.

Is there a limit to the length of a TXT record?

While theoretically very long, individual TXT record strings are often capped by practical DNS packet sizes, typically around 255 characters per string segment, though multiple segments can exist.

Is this TXT Lookup tool free to use?

Yes, Tool World's TXT Lookup tool is completely free for anyone to use, with no limits on the number of lookups you can perform.
