education university argentina
AS61496 is operated by Universidad Nacional del Centro de la Provincia de Buenos Aires (UNICEN).
What it's used for
- The address space carries university infrastructure, with the 131.221.0.0/22 block registered directly to the university and the 170.210.112.0/21 block registered to Red de Interconexion Universitaria.
- The AS announces 3072 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained academic network rather than a transit or large-scale access provider.
- Traffic from this AS consists of academic and administrative endpoints for a public university with approximately 13,000 students across three regional campuses in Tandil, Azul, and Olavarría.
Notable
- Registrants align with the announcer: 131.221.0.0/22 is registered to UNIVERSIDAD NACIONAL DEL CENTRO DE LA PROVINCIA DE BUENOS AIRES, while 170.210.112.0/21 is registered to Red de Interconexion Universitaria, a national university interconnection network.
- The address inventory is compact, consisting of two IPv4 blocks and two IPv6 /48 prefixes, typical of a single institutional campus network.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
