Summary
U.S. Bancorp
enterprise legacy
US-BANCORP belongs to U.S. Bancorp, the Minneapolis-based bank holding company behind U.S. Bank. ARIN registered the ASN in November 1993.
What it's used for
- The bank's own corporate network: internal systems, branch and office connectivity, and public-facing banking services.
Notable
- Enterprise address space. Traffic from this network is a bank's own infrastructure and staff, not consumer broadband or shared hosting.
- Large regulated financial institutions typically run their own autonomous systems so they can multi-home across providers and keep tight control over routing, which is why a bank appears this early in the AS numbering.
Interesting
- The low AS number and 1993 registration place U.S. Bancorp among the first wave of large American enterprises, as opposed to universities and government labs, to take an autonomous system of their own.
