184.108.40.206 Internetwork Packet Exchange (IPX) (NCADG_IPX)
When these extensions are enabled over the IPX datagram service, the network address MUST be either a Netware machine name or a network and node number. For more information, see [IPX].
The endpoint MUST be a 16-bit unsigned integer socket number. The network address and endpoint are not transmitted on the network by these extensions but are used by lower-layer protocols to communicate with the server.
