Summary
National Cancer Institute
government research legacy
NCIFCRF is the National Cancer Institute's autonomous system, named for the Frederick Cancer Research Facility in Frederick, Maryland. NCI is part of the US National Institutes of Health.
What it's used for
- Network connectivity for federal cancer research computing: laboratory systems, scientific data services and campus infrastructure at the Frederick site.
- The AS announces a single
129.43.0.0/16, a full Class B, which is its entire routed footprint.
Notable
- A government research network address, not a commercial one. Address space here backs federally funded biomedical research, and traffic is institutional rather than consumer.
- ARIN's registration for the ASN dates to 1995, consistent with a genuine mid-1990s allocation to a federal research campus rather than a recycled number.
Interesting
- Announcing exactly one /16 and nothing else is a distinctly old-school shape. Networks of this era were handed a Class B and simply never needed to fragment it.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
No IC3 indicators Nothing from the FBI IC3 feed.
Threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
