DomainName is the domain part of the hostname to forward.
Host is the entirety of the hostname. i.e. www.example.org
ForwardsTo is the URL this host will be forwarded to.
Type is the type of forwarding. Valid types are: Masked - This retains the original domain in the address bar and will not reveal or display the actual destination URL. If you are forwarding knowledgebase.ninja to Name.com, the address bar will say knowledgebase.ninja. This is sometimes called iframe forwarding. And: Redirect - This does not retain the original domain in the address bar, so the user will see it change and realize they were forwarded from the URL they originally entered. If you are forwarding knowledgebase.ninja to Name.com, the address bar will say Name.com. This is also called 301 forwarding.
Title is the title for the html page to use if the type is masked. Values are ignored for types other then "masked".
