What is the name for a DNS record starting with @?

I know that DNS records starting with * are called Wildcard records. What is the name for DNS record starting with @ (the at symbol). This is a record for the root domain (e.g. just example.com, not www.example.com)

I want to find out more, but searching for "@ record dns" in Google doesn't return any useful results.

What is the correct terminology for this type of record, and where might I find it described in more detail?

RFC 1035 describes the use of @ in a DNS record, but doesn't go as far as giving it a name.

This is not a question about what the @ symbol does or how it works. It is a question about the name for this kind of record.

Solution 1:

In a DNS file, the "@" symbol is a placeholder used to represent "the current domain".

The @ symbol in your DNS record refers to the record for your domain name without any www or sub-domain name.
