Summary
Kern County Superintendent of Schools
education legacy
KCSOS-NET is the Kern County Superintendent of Schools, the county office of education for Kern County, California. It runs the regional network that connects public schools across the county.
What it's used for
- Internet access and shared services for KCSOS itself and for the school districts it supports, which it serves as a regional technology provider. The county office backs dozens of districts in the Bakersfield area.
Notable
- A K-12 education network, not a university and not a commercial ISP. An IP here is typically a school, a district office, or a student device on a campus network, so it may sit behind content filtering appropriate to K-12.
- Reverse DNS resolves under
kern.org, the county office's own domain. - About 17,000 addresses are announced, sized for a county-wide school system rather than a single site.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,843 prefixes, as published 2026-11-01. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
