U.S. Army Research Laboratory
Aberdeen Proving Ground, MD, USA
The United States Army Research Laboratory (ARL), formerly known as
the Ballistics Research Laboratory (BRL), has a long history of being
a leader in the computing and networking arenas. BRL was the home of
the world's first electronic digital computer, ENIAC, and one of the
first 50 sites to have a web server on the Internet. Many BRL/ARL
researchers were involved in the early development of UNIX, the
Internet, and TCP/IP protocols (including DNS). BRL was one of the
first and one of the most well-connected nodes on the ARPANET/MILNET
back in the late 70s and early 80s. As such, BRL volunteered to host
one of the original root servers - both to assist in the further
development of DNS and to provide a root server for the MILNET in the
event that MILNET had to be disconnected from the Internet. Currently,
ARL is home to one of the world's largest supercomputing facilities
and resides on the high-speed Defense Research and Engineering Network
(DREN), which ARL scientists helped design. To this day, ARL continues
to operate a root name server as a service to the Internet community.
