Summary

Northwest Tri-County Intermediate Unit 5

United States of America · AI-generated

education government network

The AS handle NTIU5 is held by Northwest Tri-County Intermediate Unit 5.

What it's used for

  • The address space carries the internal network infrastructure for a regional educational service agency, as indicated by the netname TEN-NOWTRI-CNTY and registrant Northwest Tri-County IU 5.
  • The inventory consists of 512 IPv4 addresses across 2 prefixes, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of administrative and educational data for the 17 public school districts and nonpublic schools in Crawford, Erie, and Warren counties, Pennsylvania.

Notable

  • The RDAP registrants for both announced prefixes match the AS holder, confirming consistent ownership of the address space.
  • The address inventory is small and static, comprising two /24 blocks, which is typical for a single-organization internal network.

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 1,784 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.
