AS3152 FNAL-AS
Unclassified ARIN
Summary
Fermi National Accelerator Laboratory
government research legacy
FNAL-AS belongs to the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, the US Department of Energy's particle physics and accelerator laboratory. ARIN registered the ASN in December 1993.
What it's used for
- The laboratory's campus and scientific computing network, including the systems that store and move experimental physics data and the connections to collaborating institutions.
Notable
- Government and research address space. Addresses here belong to a national laboratory, so they represent scientific computing and staff rather than commercial or consumer traffic.
- National labs move very large volumes of experimental data between sites, which is why they run their own autonomous systems and connect to high-capacity research networks rather than ordinary commercial transit.
Interesting
- The low AS number is consistent with Fermilab's long presence on the research internet. High-energy physics was one of the fields that drove early demand for wide-area networking between laboratories and universities.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
