What is a Wildcard DNS record?

A wildcard DNS record is a record that answers DNS requests for any subdomain you haven’t already defined. You can create wildcard A records and CNAME records by entering an asterisk (*) in the host field when creating a DNS record.

For example, if you create the wildcard A record * and someone visits , their request will resolve to the IP address you specified as the answer.
