NIPRNet

NIPRNet (Non-classified Internet Protocol Router Network) is the DoD's network for transmitting unclassified but sensitive information. While not used for classified data, NIPRNet is still a controlled environment with security requirements — it's not the open internet.

Many DoD applications and services run on NIPRNet, and contractors frequently need NIPRNet access to interact with DoD systems, submit deliverables, or access government-furnished resources. NIPRNet connectivity requires compliance with DoD connection approval processes.
