Summary

Universidad de Santiago de Chile

Chile · AI-generated

education university chile

AS27897 is operated by Universidad de Santiago de Chile.

What it's used for

  • The address space is registered under the netname 158.170.0.0 - 158.170.255.255 with registrant UNIVERSIDAD DE SANTIAGO DE CHILE, indicating a dedicated institutional allocation.
  • The AS announces 65536 IPv4 addresses across 1 prefix (158.170.0.0/16) and maintains 3 observed neighbours, a ratio consistent with an access network for a single large institution rather than a transit provider.

Notable

  • The RDAP registrant matches the AS holder exactly, confirming direct ownership of the announced space.
  • The inventory consists of a single contiguous /16 block, representing a standard allocation for a major university network.

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.
