What is address?

The first thing a client needs to do to communicate with a server is to figure out who to send the data to. Where's the destination? The address is a URI that uniquely identifies a WCF end node (EndPoint), which indicates the destination of the message sent. In WCF data communication, it solves the problem of where the service is.

The composition of the address?

Address is represented in WCF by the System.ServiceModel.EndpointAddress object, which is structured as follows:

Part	Role
Uri	Indicates the address of the endpoint, is required
Identity	Can ensure the uniqueness of the address, when the URI is consistent, you can use identity to distinguish between endpoint, optional
Headers	Provides additional information for the address for the SOAP message Filter, which is then added to the header of the SOAP messages
