A records (also known as host records or address records) point a domain name or subdomain to an IP address. For example, if you want your domain "yourOwnDomainName.com" to point to your home computer (whose IP address is, for example, 192.168.0.1), the A record would list "yourOwnDomainName.com", or "@" as the host and "192.168.0.1" as the "pointing" IP address. Entering "@" for the host name is the same as entering your domain name, minus the "www". Entering "www" for the host name is the same as entering your domain name, including the "www".
To create a wildcard A record, enter an asterisk ("*") for the host name. The wildcard makes the server respond with the IP address specified instead of an error, if the subdomain queried does not exist within your zone file.
