Summary
Energy Sciences Network (ESnet)
government research legacy
A US Department of Energy research network (ESNET), operated as the Energy Sciences Network and managed by Lawrence Berkeley National Laboratory.
What it's used for
- Connecting DOE national laboratories, supercomputing facilities, and major scientific instruments to each other and to research partners worldwide, at very high bandwidth.
Notable
- A federal government science network, not a commercial ISP. The low AS number reflects an early-internet allocation from the DOE research community.
Interesting
- ESnet peers with hundreds of research and commercial networks so DOE-funded scientists can collaborate globally.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
