Atk Telecomunicações Ltda.

ATK TELECOMUNICAÇÕES LTDA. appears in Brazilian business directories under the trade name “Atualtek Telecomunicações” and is associated with multimedia communication services (SCM) in Terra Boa, Paraná. Public procurement documents also show it providing internet access services for local public entities, and one contract names Marcio Oliveira Apolinário as the company’s signatory.

The company is visible in BGP as AS52560, listed in PeeringDB as “Atualtek Telecom,” and multiple IP intelligence sources attribute IPv4/IPv6 space announcements to this ASN. Hostname patterns tied to the brand and geolocation entries place parts of the footprint in Paraná (e.g., Peabiru), consistent with a regional ISP presence.

On Reclame Aqui, “Atualtek Telecom” is shown as not verified and without a defined reputation score due to too few evaluated complaints (the page indicates very low volume in the measured period). An App Store listing for “Atualtek Internet” shows a small number of ratings with a high average, but the sample is limited, so the overall signal stays mixed/insufficient. (reclameaqui.com.br)
