What's the meaning of '@' in a DNS zone file?
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.
