The Academy operates on two separate networks – .mil and .edu. All Academy personnel, including cadets, have accounts on both networks.

Internal Coast Guard information can be found on the .mil network; it is primarily used for communication and information sharing with other Coast Guard units and personnel throughout the world. The .mil network is managed by Coast Guard Telecommunications and Information Systems Command (TISCOM) in Alexandria, Va.

The .edu network is primarily used by the cadets and faculty in support of academic studies. In Chase Hall (the cadet barracks), each room is equipped with connections to the .edu network. The .edu network is managed by the Academy's Information Services Division.

The Academy is a member of the Connecticut Educational Network (CEN). CEN provides Internet access to the .edu network. CEN also provides access to the next generation Internet2, the Connecticut Digital Library and thousands of other resources exclusively targeted to students, teachers, researchers and administrators in Connecticut’s educational institutions.

The .edu network is an optical fiber network, providing gigabit throughput to each building on campus.

Wireless connectivity is offered via the .edu network. There are numerous hot spots conveniently located throughout the campus.

The Academy is currently in the process of aquiring a connection to the SIPERNet to support both the academic program and training provided by the Leadership Development Center. SIPERNet – Secret Internet Protocol Router Network – is a system of interconnected computer networks used by the Department of Defense to transmit classified information in a completely secure environment.
