About this network

A US Department of Energy research network (ESNET), operated as the Energy Sciences Network and managed by Lawrence Berkeley National Laboratory.

What it's used for

• Connecting DOE national laboratories, supercomputing facilities, and major scientific instruments to each other and to research partners worldwide, at very high bandwidth.

Notable

• A federal government science network, not a commercial ISP. The low AS number reflects an early-internet allocation from the DOE research community.

Interesting

• ESnet peers with hundreds of research and commercial networks so DOE-funded scientists can collaborate globally.
