Summary
Universidad Nacional de Cuyo
education university argentina
AS27875 is operated by Universidad Nacional de Cuyo.
What it's used for
- The address space carries university infrastructure, evidenced by the reverse DNS record
fing.uncu.edu.arand registrant netnames explicitly namingUniversidad Nacional de Cuyo. - The AS announces 6912 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale access network for the institution rather than a transit provider.
Notable
- Registrants largely align with the announcer, with most prefixes registered to
Universidad Nacional de Cuyo, though the largest block170.210.144.0/21is registered toRed de Interconexion Universitaria. - The inventory consists of eight IPv4 prefixes of varying sizes, ranging from /21 to /24, alongside a single /41 IPv6 prefix.

Internet exchanges
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 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
