IPX

The IPX service provider uses Windows Sockets to communicate over a local area network (LAN) using the Internet Packet Exchange (IPX) protocol. The service provider supports only nonguaranteed messaging. You can use the DirectPlay protocol for guaranteed messaging on IPX. A single computer can host only one DirectPlay session using IPX.

IPX always uses a broadcast to find sessions on the network, so the service provider never displays a dialog box requesting more information.

IPX will not enumerate sessions on another subnet.

Once a session is established, packets are sent directly between computers (they are not broadcast).

The IPX service provider GUID can be specified as DPSPGUID_IPX.
