What is a TXT record?

A TXT record (Text record) is a DNS record that stores arbitrary text associated with a domain name.

In simpler terms: a TXT record is a place in DNS where you can put text information for services and checks.

#Why a TXT record is needed

TXT records are used to:

• verify domain ownership
• configure mail security
• pass service data to external services

A TXT record is not needed to open a site directly, it is needed for infrastructure and security.

#The most common uses of TXT records

#1. Mail (SPF, DKIM, DMARC)

TXT records are used to protect against spam and email forgery:

• SPF: which servers are allowed to send mail
• DKIM: a digital signature for emails
• DMARC: a policy for handling emails

Without these TXT records, emails may:

• end up in spam
• fail to reach the recipient

---

#2. Domain ownership verification

Many services ask:

"Add a TXT record with this code"

This is needed to prove:

• that you own the domain
• that you have the right to configure it

---

#3. Service information

TXT can store:

• tokens
• keys
• settings
• comments for services

DNS just stores the text, the meaning is defined by the service that reads it.

#Example of a TXT record

Simplified:

Or:

example.com TXT "google-site-verification=abc123"

#Important points for an interview

• a TXT record does not directly affect opening a site
• one domain can have several TXT records
• DNS does not interpret the text, it just returns it
• TXT is often used for security and validation

---

#Real-life example

A TXT record is like:

• a note attached to an address
• "for official use only"

The address is the domain The note is the TXT record

#Short interview answer

Remember this formulation:

A TXT record is a DNS record intended for storing arbitrary text information, which services use to verify a domain, configure mail, and handle other service tasks.
