About this network
The network of the Santa Clara County Office of Education (SCCO), run from its Information Systems Center in San Jose, California.
What it's used for
- Shared networking for public education across Santa Clara County — the county office plus the school districts and campuses it serves in the heart of Silicon Valley.
Notable
- A large holding for a K-12 agency: roughly 140,000 IPv4 addresses, including the legacy 143.254.0.0/16 and several older /18s and /19s.
- Institutional address space, aggregated on behalf of many districts rather than sold to subscribers.
Interesting
- County offices of education acting as regional network providers is a distinctly Californian pattern, and it explains why a school-district intermediary ended up with a 1994 AS number and a legacy /16.
