What it's used for
- The address space carries corporate infrastructure for a major Argentine financial institution, with reverse DNS entries pointing to
advance.com.arhosts. - The AS announces 768 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access network.
Notable
- Registrants for the announced prefixes include
Banco Rio,TELMEX ARGENTINA S.A., andTelefonica de Argentina, indicating that the bank holds space originally allocated to or associated with telecommunications providers. - Banco Río de la Plata was renamed Banco Santander Río and subsequently Banco Santander Argentina following its integration into the Santander Group.
- The inventory consists of three /24 blocks, all located in Argentina, with no IPv6 prefixes announced.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-20. 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.
