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 and BIND). 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 four 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. H was the first root server to run BIND. 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.
