126.96.36.199 SPX (NCACN_SPX)
When extensions that are not specified in sections 2.1.1 through 2.1.2 are enabled over the SPX transport protocol, the network address MUST be either a Netware machine name or a network and node number. For more information, see [IPX], IPX Addressing.
The endpoint MUST be a 16-bit unsigned integer port number. The network address of the server and the endpoint are not transmitted over the network by these extensions but are used by lower-layer protocols to set up the connection.
