UUCPNET: n. obs. The store-and-forward network consisting of all
the world's connected Unix machines (and others running some clone
of the UUCP (Unix-to-Unix CoPy) software). Any machine reachable
only via a bang path is on UUCPNET. This term has been rendered
obsolescent by the spread of cheap Internet connections in the
1990s; the few remaining UUCP links are essentially slow channels to
the Internet rather than an autonomous network. See network
address.
