Summary

Oak Ridge National Laboratory

United States · AI-generated

government research legacy

An early low-numbered allocation (ORNL-MSRNET) serving Oak Ridge National Laboratory, a US Department of Energy national laboratory in Oak Ridge, Tennessee.

What it's used for

  • Scientific, research, and operational networking for a DOE national lab.

Notable

  • A US government / national-lab network, not a commercial ISP or host.
  • The low AS number reflects an allocation from the internet's earliest years.

Interesting

  • Oak Ridge is home to some of the world's most powerful supercomputers, including systems used for large-scale scientific research.

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 1,784 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.
