Argentina · AI-generated

education university argentina

AS27981 is operated by Universidad Nacional de Mar del Plata.

What it's used for

  • The address space carries university infrastructure, evidenced by reverse DNS entries such as cecom128.mdp.edu.ar and admin255.mdp.edu.ar.
  • The AS announces 1536 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small-scale access network for an educational institution.

Notable

  • Both registrants for the announced prefixes (170.80.24.0/22 and 200.0.182.0/23) match the AS holder, Universidad Nacional de Mar del Plata.
  • The inventory consists of two distinct IPv4 blocks with no IPv6 prefixes announced.

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 2026-10-24. 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.
