AS3152 — FNAL-AS

AS3152 announces 3 IPv4 prefixes covering 66,816 addresses and 1 IPv6 prefixes.

About this network

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.
