Chile · AI-generated

financial business chile private

AS27918 is operated by Sistema Nacional de Comunicaciones Financieras S.A.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS records pointing to the sncf.cl domain.
  • The network announces a single IPv4 prefix of 256 addresses with 2 observed neighbours, indicating a small, self-contained business network rather than a transit or access provider.

Notable

  • The RDAP registrant matches the AS holder exactly, confirming direct ownership of the announced space.
  • The inventory consists of a single /24 block, representing a compact and focused address allocation typical of a specialized corporate entity.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
