Summary

Universidad Nacional de Córdoba

Argentina · AI-generated

education university research argentina

AS27790 is operated by Universidad Nacional de Córdoba.

What it's used for

  • The address space carries university infrastructure, evidenced by the reverse DNS record alumnos.derecho.unc.edu.ar and the registrant netname 200.16.16.0 - 200.16.31.255.
  • The AS announces 6144 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 5 observed neighbours, indicating a regional educational network rather than a transit provider.

Notable

  • Registrants include Universidad Nacional de Cordoba for the primary block and Red de Interconexion Universitaria for the secondary block, reflecting the university's participation in Argentina's national academic network.
  • The inventory consists of two distinct IPv4 ranges: 200.16.16.0/20 and 170.210.248.0/21, alongside the IPv6 prefix 2801:120::/32.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
