Summary

Allegheny Intermediate Unit

United States · AI-generated

education legacy

AIU-ALLEGHENY-CONNECT-RWAN belongs to the Allegheny Intermediate Unit (AIU), a public educational service agency serving the school districts of suburban Allegheny County, Pennsylvania, around Pittsburgh.

What it's used for

  • The regional wide-area network ("Allegheny Connect") that links member school districts: internet access, shared services, and inter-district connectivity for K-12 schools.
  • Announces a small legacy IPv4 footprint, on the order of a couple of thousand addresses.

Notable

  • K-12 education address space, aggregated. An intermediate unit is a middle layer of Pennsylvania's school system that buys and operates services on behalf of many districts at once, so traffic from this ASN comes from schools rather than from a single institution or from consumers.
  • Schools reached through this network sit behind district firewalls and content filtering, which makes the traffic profile distinctly different from a university's.

Interesting

  • It shares its AS-number neighbourhood with a run of Pennsylvania higher-ed networks — AS3778 (Temple University), AS3782 (Swarthmore College) — a reminder that the state's education networks, K-12 included, came online as a cohort.

Classification and threat

Education University, school or national research and education network.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
