Unclassified LACNIC
Summary
ATL Comercio e Servicos de Informatica Ltda
telecom residential brazil
AS52543 is operated by ATL Comercio e Servicos de Informatica Ltda.
What it's used for
- The address space carries subscriber traffic, evidenced by reverse DNS records pointing to
microsattelecom.com.br(e.g.,179-107-64-128.microsattelecom.com.br). - The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small access or eyeball network rather than a transit provider.
- Traffic from this AS consists of end-user internet access, consistent with the operator's role as a telecommunications service provider in Brazil.
Notable
- Registrants for both announced IPv4 prefixes (
179.107.64.0/23and179.107.70.0/24) match the AS holder, ATL Comércio e Serviços de Informática Ltda. - The address inventory is compact, consisting of two contiguous IPv4 blocks and a single large IPv6 allocation.

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 2026-11-01, 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: 447 networks and 1,843 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.
