Summary

Universidad de Chile

Chile · AI-generated

education research university

AS23140 is operated by Universidad de Chile, the public university in Santiago.

What it's used for

  • The address space carries university infrastructure, evidenced by reverse DNS entries such as 146-83-55-254-LIBRE.uchile.cl, 200-89-75-254-STI.uchile.cl, and ip128.cmm.uchile.cl.
  • The AS announces 20,992 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, indicating a self-contained educational network rather than a transit provider.

Notable

  • Registrants include Red Universitaria Nacional for the bulk of the 146.83.0.0/16 space, alongside specific university departments like University of Chile, Computer Sciences Department and Facultad de Ciencias Físicas y Matemáticas de la Universidad de Chile.
  • The inventory is dominated by the 146.83.0.0/16 block, which is subdivided into multiple prefixes registered under the national university network, reflecting a shared academic infrastructure.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
