Summary

Marian University

United States of America · AI-generated

education business university

The AS handle MARIANU-IN is held by Marian University.

What it's used for

  • The address space carries university infrastructure, with netnames ILIGHT-NET-199-8 (Indiana Higher Education Telecommunication System) and MU-147 (Marian University).
  • The AS announces 2560 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, indicating a small, self-contained institutional network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of campus network traffic for students, faculty, and staff, including web services, research endpoints, and administrative systems for the university's Indianapolis campus.

Notable

  • Registrants align with the announcer: Indiana Higher Education Telecommunication System (IHETS) for the larger block and Marian University for the smaller block, reflecting the university's participation in the state higher education network.
  • The inventory consists of two distinct IPv4 prefixes: 199.8.160.0/21 and 170.76.232.0/23, with no IPv6 prefixes announced.

Reputation

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
