Summary
ESnet (Energy Sciences Network)
government research legacy
An Energy Sciences Network (ESNET-AS) autonomous system. ESnet is the US
Department of Energy's science network, linking DOE national laboratories and
research facilities to each other and to the wider internet.
What it's used for
- Research and laboratory networking for the DOE complex, with a small announced footprint on this particular AS number.
- No commercial customer base. ESnet exists to serve the department's science mission.
Notable
- Government research address space, not a consumer or hosting network.
- ESnet's sibling registrations: [AS3425](https://asn.ipinfo.app/AS3425), [AS3428](https://asn.ipinfo.app/AS3428), and [AS3443](https://asn.ipinfo.app/AS3443).
- Holding several adjacent low AS numbers is itself a fingerprint of an early, large, multi-site network that grew up alongside the internet.
