Summary
National Institutes of Health (NIH)
government research legacy
NIH-NET, the network of the US National Institutes of Health, the federal
government's principal medical research agency, headquartered in Bethesda,
Maryland.
What it's used for
- Campus and research networking across the NIH intramural programme — labs, the Clinical Center, and the institutes and centres that make up NIH.
- Public-facing NIH services such as PubMed and the National Library of Medicine sit behind NIH's networks.
Notable
- Government and research address space (roughly 325,000 IPv4 addresses) — a large institutional allocation rather than a commercial one.
- Traffic here is overwhelmingly institutional: researchers, hospital systems, and public biomedical data services, not residential subscribers.
Interesting
- Registered with ARIN in 1994, from the era when large federal science agencies connected to the internet directly rather than through a commercial carrier.
