Summary
St. Michael's Hospital
enterprise legacy
SMH-ASN belongs to St. Michael's Hospital in Toronto, Ontario, a large
downtown teaching hospital now part of Unity Health Toronto.
What it's used for
- The hospital's own network: clinical and administrative systems, research groups, and its public-facing web services.
- A small announced footprint, consistent with a single institution running its own address space rather than reselling connectivity.
Notable
- This is institutional healthcare address space. Traffic from it is hospital staff, clinicians, researchers, or hospital-run servers, not home broadband.
- A low four-digit AS number is unusual for a hospital and points to an early allocation, from a period when Canadian research and teaching institutions were among the first non-carrier networks online.
Interesting
- St. Michael's is one of the Greater Toronto Area's adult trauma centres and is affiliated with the University of Toronto, which puts a research and academic workload alongside the clinical one on the same network.
