About this network

ESNET-AS is the Energy Sciences Network, the US Department of Energy's high-performance science network. ESnet connects the DOE national laboratories and their research collaborators to each other and to the rest of the internet.

What it's used for

• Moving very large scientific datasets between national labs, supercomputing centres, and experimental facilities.
• Serving DOE research sites rather than any commercial customer base. ESnet is a mission network, not an ISP.

Notable

• ESnet holds several AS numbers in this range. See also AS3428, AS3431, and AS3443.
• This is government research address space. Traffic from it is laboratory staff and scientific infrastructure, which is why it behaves very differently from consumer or hosting ranges.

Interesting

• ESnet's design goal is the opposite of a typical ISP's: it is engineered for a small number of enormous, sustained data transfers rather than a large number of small ones.
