Summary

Universidad Nacional del Litoral

Argentina · AI-generated

education university argentina

AS27993 is operated by Universidad Nacional del Litoral.

What it's used for

  • The address space is registered under the netname 190.122.240.0 - 190.122.255.255 with registrant Universidad Nacional del Litoral, indicating internal institutional use.
  • The AS announces 4096 IPv4 addresses across 1 prefix (190.122.240.0/20) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained campus network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant matches the AS holder, confirming direct ownership of the announced space.
  • The inventory consists of a single contiguous /20 block, typical of a university's internal network segmentation.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
