Summary

Twin Rivers Unified School District

United States of America · AI-generated

education k12 california school

TWINRIVERS-USD is operated by Twin Rivers Unified School District, a public school district serving the Sacramento area in California.

What it's used for

  • The address space carries internal district infrastructure, with netnames SWI-TWINRIVERS-1 and SCOOPNET indicating specific network segments or service blocks.
  • The AS announces 1024 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of staff, student, and administrative endpoints for the district's schools and offices, including web services, learning management systems, and internal administrative tools.

Notable

  • Registrants for all announced prefixes align with the announcer, listing "Twin Rivers Unified School District" and "Twin Rivers USD".
  • The address inventory is compact, consisting of one /23 and two /24 blocks, all located in the United States.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
