Defense Data Network
The Defense Data Network (DDN) was a separate instantiation of the ARPANET used by the United States Department of Defense from 1983-1995 for its Internet services.
The DDN began as the MILNET, a network formed in 1983 when military sites split off the public ARPANET. As a large-scale, private internet, the DDN provided Internet Protocol connectivity across the United States and to US military bases abroad. Throughout the 1980s it expanded as a set of four parallel military networks, each at a different security level. These networks transitioned to become the NIPRNET, SIPRNET, and JWICS networks in the 1990s.
