Summary

University of Maribor

Slovenia · AI-generated

education university slovenia

UM is operated by University of Maribor.

What it's used for

  • The address space carries university infrastructure, evidenced by the netname UNI-MB-NET and reverse DNS entries like szrd.feri.um.si pointing to the Faculty of Electrical Engineering and Computer Science.
  • The AS announces 61,440 IPv4 addresses across 4 prefixes with only 1 observed neighbour, indicating a single-site or internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of academic research, administrative services, and student/staff connectivity within the university campus.

Notable

  • All registrants for the announced prefixes are consistent, listing IRT-SI-CERT; Univerza v Mariboru; University of Maribor NOC.
  • The address inventory is finely subdivided into four contiguous blocks within the 164.8.0.0/17 range, reflecting internal segmentation for different faculties or departments.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
