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.ar and 201-234-19-64.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 (186.0.160.0/20 and 201.159.56.0/21) match the announcer, Grupo Servicios Junin S.A., while smaller prefixes (201.234.19.0/24 and 201.234.101.0/24) 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.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
