RemoteEndpointMessageProperty Class

Makes available the client IP address and port number associated with the remote endpoint from which a message was sent.

Namespace:  System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

Public NotInheritable Class RemoteEndpointMessageProperty
Dim instance As RemoteEndpointMessageProperty

The property is added to each incoming message to a Windows Communication Foundation (WCF) service through both the HTTP and TCP transports.

The property is not present on messages received through either a named pipes or MSMQ transport.

Availability of the property when using HTTP hosted in IIS depends on having a currently active request.  Therefore, this property is not available after the request has completed, such as when performing a one-way receive.

The IP address and port number are that of the node from which the message was received. If a message goes through a relay or proxy, the IP address and port number of the respective relay or proxy is the one attached to the message by this property.

Be aware that the IP address and port could be spoofed by an attacker and thus should not be relied upon for security sensitive authentication or authorization unless additional application specific logic is added.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
