The connection address defines exactly who may access the
web service. When localhost is selected, the web service will only be
available from the local PC. Alternate possible selections are each (IPv4),
each (IPv6), or the manual input of a specific IP address. Select
localhost if you wish to test your first web service locally.
Port defines under which TCP port the web service should be
available. Ideally, use a port number between 49152 and 65535, one of the
so-called private ports. These can be variably used, as they are not
registered and therefore do not belong to a specific application.
Host and Port together constitute the endpoint URL,
under which your web service will be available. The web service can be
integrated easily into your domain for public use.
With the Provider Active setting, your web service will be immediately available, i.e.
retrievable, under the indicated endpoint URL.
