Summary
ESnet (Energy Sciences Network)
government research legacy
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](https://asn.ipinfo.app/AS3428), [AS3431](https://asn.ipinfo.app/AS3431), and [AS3443](https://asn.ipinfo.app/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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
No IC3 indicators Nothing from the FBI IC3 feed.
Threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
