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.
