I will ask if there is no problem in terms of adding a TXT record for DNS using the domain of example.com as an example.
Owner domain: example.com
DNS record information
| Subdomain | Type | value |
|---|---|---|
| A | xxx.xxx.xxx.xxx | |
| www. | CNAME | example.com |
| MX | example.com | |
| TXT | v = spf1 ip4: xxx.xxx.xxx.xxx -all |
Add the following record for the above settings.
| Subdomain | Type | value |
|---|---|---|
| TXT | 0123456789ABCDEF |
Reasons for adding
With the use of a certain external service, it is mandatory to confirm domain ownership.
For such confirmation, subdomain is generally specified, but this time there is no subdomain designation.
Setting multiple TXT records for the host name (example.com) would violate DNS record rules, etc ....
I am worried about
If there is no problem, I hope ...
If i have any information, please give me a professor.

You can write as many lines as you like on the TXT record itself
For example, StackOverflow.com TXT record
And there should be no more than one SPF or more than one google-site-verification
