Summary
ESnet (Energy Sciences Network)
government research legacy
An Energy Sciences Network (ESNET-AS) autonomous system, announcing a
single small prefix. ESnet is the US Department of Energy's high-performance
network for its national laboratories and science facilities.
What it's used for
- DOE research networking. This AS number carries a minimal footprint, the kind typically used for a specific site or function rather than a broad backbone role.
Notable
- Government research address space, tied to the DOE laboratory complex rather than to any commercial service.
- Other ESnet AS numbers nearby: [AS3425](https://asn.ipinfo.app/AS3425), [AS3428](https://asn.ipinfo.app/AS3428), and [AS3431](https://asn.ipinfo.app/AS3431).
Interesting
- Very small announced footprints on legacy AS numbers are common: the number was allocated when policy was loose, and the network kept it even as its actual routing consolidated elsewhere.
