The ARPANET was decommissioned in 1990. The existence of NSFNET and the creation of Federal Internet Exchanges (FIXes) allowed the ARPANET to be decommissioned in 1990. 1990 Mike Karels, Phil Almquist, and Paul Vixie have maintained BIND since then. BIND was ported to the Windows NT platform in the early 1990s.
The ARPANET was decommissioned in 1990 after 30 years of experimentation and service. In those years the ARPANET dramatically demonstrated the feasibility and efficiency of packet switching communication, the desirability and productivity of resource sharing and the value of open standards and collaborative research and development. The great success of computer communications owes a great deal to the vision and scientific and engineering skill of the ARPANET pioneers.
