I have one question to define the dns records. In this url (https://cloud.google.com/dns/docs/records), I read
Note: Adding the @ symbol in this field causes the record to fail.
This generates some doubts, until now whenever I had defined the records in Google Cloud DNS, instead of using @ I left it empty (thus referring to $ ORIGIN)
This is so?
that is, for example
example.com. 300 IN TXT "v = spf1 xxxxxxxxxxxxxxxxxxxxxxxxx"
example.com. 300 IN MX 10 server.domain.com.
Thank you very much
