Summary
The Children's Hospital of Philadelphia
enterprise research legacy
CHOP is The Children's Hospital of Philadelphia, the United States' first hospital dedicated to paediatric care and one of the largest paediatric research institutions in the country.
What it's used for
- The hospital system's own enterprise network: clinical systems, the main and satellite campuses, staff access, and the research institute's computing.
- It announces
159.14.0.0/16plus a few more-specifics, giving roughly 64,000 addresses — a large block by hospital standards, reflecting a combined care and research organisation with an extensive campus footprint in West Philadelphia.
Notable
- This is an institutional network, neither an ISP nor a host. Traffic behind it is hospital staff, clinical and biomedical research systems, not consumers.
- Registered with ARIN in November 1996, in the same sequential run as several neighbouring numbers, and still held by the hospital.
Interesting
- Hospitals rarely run their own AS. CHOP does because it is effectively a research university's worth of computing attached to a health system, with peering and research-network requirements to match.
