Catchall and @ Records

Two special records exist to aide in name resolution and directing clients to a specific resource. They are the “at” record, denoted by the @ symbol, and a catchall record denoted by the asterisk symbol (*). The @ record is commonly used for domain website addresses. This allows a user to type test.com into a web browser and get back the same IP as if they had typed www.test.com. The default behavior is to build an @ record from the Host Name www, though this behavior can be overridden by manually specifying an @ record.

The catchall record allows a client to be directed to a resource if they use any host name that is not defined in the zone. This can be useful to maintain a web presence regardless of host name typos. For example, ww.test.com or non-existent-host.test.com will all return the IP addresses specified by the asterisk (*).
