Hostname Resolutions
Override DNS resolution for hosts.
In some cases it may be useful to override the IP address that a hostname resolves to, for example, when developing an application that is still deployed locally. Any IP addresses set up here will override results from actual DNS resolution.

You can use wildcards in you hostnames, for example:
*
matches to any hostname*.example.com
matches to any subdomain of example.com?.example.com
matches to any one letter subdomain of example.com
Note that only the first matching hostname resolution will be used.
