Because it is not IP based.
NetBEUI is the only listed protocol that is not routable; the rest are.

It's not routable network + Guide to networks pg196
A routable protocol contains a network address as well as a device address. Non-routable protocol, on the other hand, regulate the transfer of data and always makes use of interior routing system to transmit data.
when is NetBIOS routable
No, not all protocols are routable.
NetBIOS Frames (NBF) protocol is non routable.
Windows XP does not automatically install NetBEUI, as Microsoft considers it a legacy protocol.
The Transport Layer
A non-routable protocol has less overhead and processing to do, and is more compact. This leads to faster transmission.
No it's in the private range.
NON-ROUTABLE PROTOCOLS cannot survive being routed. Non-routable protocols presume that allcomputers they will ever communicate with are on the same network (to get them working in a routed environment, you must bridge the networks). Todays modern networks are not very tolerant of protocols that do not understand the concept of a multi-segment network and most of these protocols are dying or falling out of use.NetBEUIDLCLATDRPMOP
