IPX runs at layer 3. There's no question of that.
Perhaps the confusing thing is that IPX layer-3 addresses consist of
network.MAC. The node part of the address is the same as the layer-2 NIC
address, also known as MAC or hardware address.
This means that IPX doesn't need an ARP. If you know the Layer-3 address,
you know the Layer-2 address also.
Above IPX, the most common Novell protocol is NetWare Core Protocol (NCP)
used by file servers. Print servers use SPX. It's a myth that NCP uses SPX.
It doesn't.
