How to Update TXT and SPF Records - DNS Management

Sender Policy Framework and the related TXT files are used to verify domain ownership and implement email security measures to reduce spam and domain spoofing. It is a DNS record that provides text information to sources outside the domain that can be used for several purposes. The record's value can be either human- or machine-readable text. 
 

v=spf1	mx	include	ip4:66.96.128.0	-all
Sets the SPF version being used.	Allows the domain’s MX details to send an email.	Includes Google mail servers as authorized servers.	This IP address will pass.	Any other IP address will fail.

SPF vs TXT

An SPF TXT record is a DNS record that verifies the domain name from which email messages are sent, thereby preventing spoofing and phishing. SPF validates the origin of email messages by comparing the sender's IP address to the alleged owner of the sending domain. It is suggested that SPF records be regenerated as TXT SPF records as they are no longer supported. From this perspective, we can claim that by their very nature, these SPF records are likewise TXT records. However, they are used specifically for email.
 
TXT records, on the other hand, have a far broader range of applications. TXT records can also be used to publish DKIM and DMARC records, as well as to demonstrate domain ownership.
