What is TXT record?

A TXT record is a form of resource record in the Domain Name System which is used to associate arbitrary text with either a host or other name. The TXT record is commonly used for verification as well as email validation. This includes human readable information related to network, server, data center etc.

An example of TXT record:

v=spf1 include:_spf.google.com ~all

Every record can have either one or more than one-character strings. Traditionally, these text fields were used for number of non-standardised uses including an organisation’s name or the address of a host.

TXT records are used for Sender Policy Framework (SPF), DomainKeys, DomainKeys Identified E-mail (DKIM) as well as DMARC. These records are dynamic as well as can be used for several purposes. TXT records are not used to direct traffic but are used for providing required information to outside sources.

A domain can have more than one TXT records associated with it if DNS server implementation supports this. A TXT record does not have any direct impact on the way your domain functions. Rather, it tells services about your domain and how was it set up or what services are used by the domain. These records have replaced SPF records.

Common uses for TXT records include:

Type Description

DKIM record The record stores important information which used for the validation of email in transit.

DMARC record DMARC records help in mitigating email spoofing attacks.

SPF record The record is used for indicating to mail exchanges about hosts that are authorized to send mail for the domain.

Site Verification Records This record helps in proving the ownership of a domain and it can also be used for associating services including G-Suite or Microsoft 365 to a specific domain.

With the help of KDMARC, TXT records are displayed in detail so that these can be analysed in detail by the organizations.
