Summary
Acerca
isp residential regional argentina
AS52255 is operated by Grupo Servicios Junin S.A., known commercially as Acerca.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
0.164.0.186.acerca.com.arand201-234-19-64.static.impsat.net.ar. - The AS announces 6,656 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining only 3 observed routing neighbours, a ratio indicative of a regional access provider rather than a transit carrier.
- Traffic from this network consists of subscriber eyeballs for cable, DSL, and fixed wireless services in the Junín region of Argentina.
Notable
- Registrants for the largest prefixes (
186.0.160.0/20and201.159.56.0/21) match the announcer, Grupo Servicios Junin S.A., while smaller prefixes (201.234.19.0/24and201.234.101.0/24) are registered to Cirion Technologies Argentina S.A. - The address inventory includes a large /20 block and a /21 block, alongside smaller /24 allocations, reflecting a mix of legacy and newer address space.

Internet exchanges
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 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
