TXT Record
A TXT Record (Text string) is the segment of DNS data that stores textual information about the domain system. This includes the hostname, IP address, and port number.
What TXT records are for
You will probably only come across TXT Records when you have to confirm your rights to a domain that you have just purchased. To do so, you need to go to the registrar's website and add the confirmation code (authInfo-code) to the DNS record of the domain purchased.
Text records in DNS also often contain:
- DKIM keys to encrypt the contents of emails;
- SPF records to show that the domain name is not being used to send spam;
- DMARC records, which are used to manage emails that have not passed DKIM or SPF validation;
- an MTA-STS standard, which is responsible for the security of an SMTP connection;
- a BIMI standard that adds logos to emails.
Additional DNS TXT records come in useful every time you need to connect an additional service or verify the rights to the domain.
TXT records ensure that both computers and humans can quickly and conveniently work with data in DNS. The server can quickly read the TXT, and the operator can easily add or edit parameters to it.
How to add a TXT Record
You can create a new TXT record in the "Manage DNS" section of ispmanager. After selecting the required domain in the context menu, click the "Manage DNS records" button.
Next, a form will open where you can create a new record. You will have to specify the name of the subdomain, the type and the time in which to store the record in the cache.
If the records do not conflict with one another, it is possible to add an unlimited number of TXT Records to DNS. However, domain registrars often set a limit of 49 TXT records.
