Summary
ESnet (Energy Sciences Network)
government research legacy
One of the Energy Sciences Network (ESNET-AS) autonomous systems. ESnet is
the US Department of Energy's science network, connecting the national
laboratories and their research collaborators. This is the largest of ESnet's
low-numbered AS registrations by announced address space.
What it's used for
- Carrying research traffic for DOE laboratories and user facilities: large scientific data transfers, remote instrument access, and lab site connectivity.
- Serving the DOE research mission rather than commercial subscribers.
Notable
- This is government research address space. Hosts in it are lab systems and scientific infrastructure, not eyeball broadband or commercial hosting.
- ESnet's other AS numbers in this range: [AS3425](https://asn.ipinfo.app/AS3425), [AS3431](https://asn.ipinfo.app/AS3431), and [AS3443](https://asn.ipinfo.app/AS3443).
Interesting
- Research and education networks like ESnet routinely carry per-flow volumes that would be extraordinary on a commercial network, because a single physics or genomics experiment can produce petabytes that must move between sites.

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.
