About this network

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.
