The Ultimate Guide to TXT DNS Records

TXT DNS Records: A Comprehensive Guide

Txt Dns Records

TXT DNS records are a type of Domain Name System (DNS) record that allows you to associate arbitrary text with a domain or subdomain. They are primarily used to provide additional information about a domain to other systems, such as email servers, web browsers, and security services.

What are TXT DNS Records?

When it comes to managing your domain’s DNS records, one type that often gets overlooked is the TXT (Text) record. While commonly used for email authentication and domain ownership verification, TXT records have a wide range of applications that can benefit your website’s security, email deliverability, and overall online presence. In this article, we will explore the ins and outs of TXT DNS records, their uses, and how to effectively implement them.

Common Uses of TXT DNS Records

TXT records have a variety of uses, but here are some of the most common ones:

  • Email Authentication: TXT records are widely used for email authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). These records help prevent email spoofing and improve email deliverability.
  • Domain Ownership Verification: When you need to verify your domain ownership for services like Google Search Console or email marketing platforms, you often need to add a specific TXT record to your DNS settings.
  • Website Security: Some security services, such as SSL certificate providers, require you to add a TXT record to your DNS settings to prove domain ownership before issuing the certificate.
  • SPF Records: Sender Policy Framework (SPF) records are TXT records that specify which servers are authorized to send email on behalf of your domain. They help prevent email spoofing and improve email deliverability.
  • Custom Information: TXT records can also be used to provide custom information about your domain, such as contact details, copyright notices, or even ASCII art.

Implementing TXT DNS Records

Implementing TXT DNS records is a relatively straightforward process. Here’s a step-by-step guide:

  1. Access your domain’s DNS management interface. This is usually provided by your domain registrar or hosting provider.
  2. Locate the section for managing DNS records.
  3. Create a new TXT record by selecting the “Add Record” or similar option.
  4. Enter the necessary information, including the hostname (e.g., “” or “”) and the text value.
  5. Save the changes and wait for the DNS propagation to complete. This can take anywhere from a few minutes to several hours.
  6. Verify the record using online DNS lookup tools or by checking the specific service that requires the TXT record.

Real-World Examples

Let’s take a look at a couple of real-world examples to illustrate the practical applications of TXT DNS records:

Email Authentication with SPF

Suppose you want to improve your email deliverability and prevent others from sending unauthorized emails on behalf of your domain. In that case, you can create an SPF TXT record that specifies the authorized email servers for your domain. Here’s an example: IN TXT "v=spf1 ~all"

This record tells receiving email servers that only the servers listed in “” are authorized to send emails on behalf of “”. The “~all” mechanism indicates that any other servers should soft-fail, meaning they may still deliver the email but mark it as potentially suspicious.

Domain Ownership Verification with Google Search Console

When verifying your domain ownership in Google Search Console, you may be asked to add a specific TXT record to your DNS settings. The record will look something like this:


By adding this TXT record, you prove to Google that you have control over the domain and gain access to valuable search performance data and configuration options.


TXT DNS records are a versatile tool that can enhance your domain’s security, email deliverability, and online presence. Whether you need to authenticate your emails, verify domain ownership, or provide custom information, TXT records offer a simple and effective solution. By understanding their uses and implementing them correctly, you can ensure a smooth and secure online experience for your website and its visitors.
