Unclassified ARIN
Summary
Sandia National Laboratories
government research legacy
SNLL-NET-AS, a network of Sandia National Laboratories, the US Department of Energy / NNSA national laboratory. The SNLL in the handle refers to Sandia's Livermore, California site (the lab's main campus is in Albuquerque, New Mexico).
What it's used for
- Research and institutional networking for Sandia: engineering, computing, and the national-security science programs the lab carries out for the DOE's National Nuclear Security Administration.
Notable
- A large institutional allocation (roughly 132,000 IPv4 addresses) — government and research address space, not commercial.
- Sandia is a federally funded research and development centre, so this network sits alongside those of the other DOE labs rather than in the commercial internet.
Interesting
- Registered with ARIN in 1994. The US national laboratories were among the earliest internet sites, and several still hold AS numbers well under 5000.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
