NMIS History

NMIS (Network Management Information System) is an open-source network management system originally written by Keith Sinclair and was first released in 1998. The intellectual property for NMIS was purchased by commercial open source software company Opmantek in early 2011 under a stated commitment (which continues) to keep “NMIS free and lead the community to rapidly advance the product”. All versions of NMIS since 2011 remain free and open source. On the 24th of June 2020, Opmantek released NMIS 9.
