Data Division (NS1) provides interoperable, secure and non-secure Internet Protocol (IP) data communications services.

NIPRNet: The Unclassified but Sensitive Internet Protocol (IP) Router Network (NIPRNet) is a global long-haul IP-based network to support unclassified IP data communications services for combat support applications for the Department of Defense (DoD), Joint Chiefs of Staff (JS), military departments (MILDEPS), and combatant commands (COCOM). Provides seamless interoperability IP services to customers with access data rates ranging from 56kbps to 1.0Gbps via direct connections to a NIPRNet router, remote dial-up services (56kbps), services to the tactical community via ITSDN/STEP sites, and access to the Internet.

SIPRNet: The Secret IP Router Network (SIPRNet) is DoD’s largest interoperable command-and-control data network, supporting the Global Command and Control System (GCCS), the Defense Message System (DMS), collaborative planning, and numerous other classified warfighter applications. Direct connection data rates range from 56 kilobytes per second kbps to 1.0 gigabytes per second Gbps. Remote dial-up services are available up to 115kbps, and services to the Tactical community are available via ITSDN/STEP sites.

Network Information Center/SIPRNet Support Center (NIC/SSC): The DISA-managed g-Root, one of 13 global Internet Roots, resolves more than 236 billion DNS queries annually. The .mil/.smil DNS servers resolve more than 22 billion queries annually. The .mil DNS environment availability in 2008 was 100%, and g-Root availability was 99.998%. More than 14,000 customer actions involving Domain and IP Address requests are handled annually. More than 30,000 authentication actions are handled for the DISN dial access for NIPRNet and SIPRNet annually. More than 270,000 web inquiries and 190,000 WhoIs database inquires are directed to the DoD NIC/SSC servers annually.

Defense Information Systems Network-Leading Edge Services (DISN-LES): DISN-LES is a Mission Assurance Category III program designed to pass encrypted unclassified and classified traffic over the Classified Provider Edge (CPE) routers of the DISN, and provide capability for subscriber sites requiring "next generation" network, encryption, software, NETOPS, and advanced services not offered by other DISN Subscription Services (DSS). The network provides a non-command-and-control, risk aware infrastructure identical to the core DISN data services (NIPRNet and SIPRNet). It is available to subscribers of a variety of communities of interest to support a "test-once" capability test and evaluation (T&E), interoperability, information assurance, certification and accreditation (C&A), and operational T&E (OT&E) environment which would include developmental (DT), interoperability (IOP), information assurance (IA) and net-centric key performance parameter (NR-KPP) compliance testing of capabilities, systems, equipment, network monitoring and management technologies, data link compliance, and compatibility testing among products produced on evolving standards for systems planned for the operational community.  The results of network, hardware and software tests, and exercises are shared with equipment and software suppliers and government organizations to provide a Net-Centric real world experience with the technologies that influence network designs and system acquisition decisions throughout the industry.

Anti-Drug Network (ADNET): The ADNET Program Management Office implements information systems technologies (C4I) and services at the secret and sensitive but unclassified (SBU) levels for federal, regional, state, local, tribal and foreign partners to support the counter-narcoterrorism (CNT) mission as directed by the office of the deputy assistant secretary of defense for Counternarcotics, Counter proliferation, and Global Threats.  The ADNET Program management office provides application services to include, asynchronous and synchronous collaboration, data visualization, data analysis, and customized development as well as enterprise and customer enclave support to include certification and accreditation, information assurance engineering, and operational sustainment for CNT customers.
