Summary

  • AS267241, the autonomous system tied to the AI Brazil name, originates one IPv4 prefix (45.232.28.0/22, 1,024 addresses), zero IPv6 prefixes, with one upstream and no visible downstreams — unchanged across every mirror checked for this report.
  • The network is registered to CNPJ 15.644.251/0001-86, GMAES TELECOM LTDA EM RECUPERACAO JUDICIAL, a small company in judicial recovery based in Itajaí, Santa Catarina; the brand entity, AI.BRAZIL TECHNOLOGIES & DATACENTER LTDA, is a different CNPJ founded in 2022 in Balneário Camboriú.
  • The verifiable business of the brand is municipal cloud and SaaS contracts — from R$1,314 in Ilhabela to R$450,900 in Pomerode in 2026 — not GPU-bearing datacenter capacity.
  • The AS-owning CNPJ carries a temporary-supplier-suspension sanction in Brazil's federal SICAF system, sanctioned by the Conselho Federal de Medicina Veterinária.
  • No public record examined for this report documents compute hardware, power contracts, colocation space or any other physical ingredient of an AI datacenter under either CNPJ.

The question this report asks is deliberately narrow. Not whether the company is legal, and not whether municipal cloud contracts are legitimate business — they are ordinary procurement. The question is what, in the public record, distinguishes "AI BRAZIL TECHNOLOGIES & DATACENTER LTDA" from any other small software house selling email and storage to city halls, and what observable evidence would have to appear before the "AI datacenter" part of the name could be treated as a description rather than a label.

Two registers, one name

Brazilian company records and internet-number records are separate worlds, and the AI Brazil name sits at their intersection in an unusual way. In the corporate world, two distinct CNPJs matter. The brand entity, AI.BRAZIL TECHNOLOGIES & DATACENTER LTDA (trade name AIBR), is CNPJ 45.908.107/0001-70, active since 5 April 2022, registered at Rua 1500, 820, Sala 2002, Edifício Sky Business Center, Centro, Balneário Camboriú, Santa Catarina, under CNAE 6311900 — data processing, application-service provision and internet hosting — with sole administrator GESSICA MAES FERREIRA SILVA since 16 October 2023 GuiaPJ registry mirror.

The network world points elsewhere. The autonomous system AS267241 is registered under CNPJ 15.644.251/0001-86 — GMAES TELECOM LTDA EM RECUPERACAO JUDICIAL, trade name Grupo Entel, opened 28 May 2012, a small company with R$100,000 in capital headquartered in Itajaí, Santa Catarina, administratively active per Receita Federal data updated 10 April 2026 MonitorCNPJ registry record. The two CNPJs are different companies on paper. The link between them is a person: the registry contact handle on the AS object belongs to Gessica Maes Ferreira Silva, the same name that appears as sole administrator of the brand CNPJ IPIP.NET whois mirror.

What the routing record shows

Whatever the corporate paperwork says, the routing table is the harder evidence, because it cannot be edited by marketing. On every mirror checked for this report, AS267241 announces exactly one IPv4 prefix, 45.232.28.0/22 — 1,024 addresses — and no IPv6 prefixes at all. Hurricane Electric's IPv4 view counts one originated v4 prefix, 1,024 originated addresses, zero v6 prefixes and zero v6 AS paths, with 684 observed IPv4 AS paths at an average length of 5.661 Hurricane Electric IPv4 view. CIDR Report independently shows one upstream, zero downstreams, 1,024 originated addresses and a single announced prefix with no withdrawals CIDR Report AS report.

A single upstream is BIT7NET TECNOLOGIA E SERVICOS LTDA, AS264324 Hurricane Electric AS view. For context, an AI datacenter operator with even modest GPU capacity typically needs transit diversity, peering at internet exchange points, and address space that grows with the cluster. This network has none of those properties visible in public routing data. CAIDA's AS Rank maps the organization to a single member ASN, one prefix, 1,024 addresses and zero transit degree BTW case file, 26 September 2026, citing CAIDA AS Rank and the Milagres e-SUS contract.

Routing security tells the same story from another angle. Both route objects for this ASN — the IPv4 45.232.28.0/22 and the IPv6 2804:4a74::/32 — are third-party customer-proxy objects created by other operators' registration staff (Commcorp Telecom, changed 2025-02-05; BR.Digital, changed 2025-10-14; source RADB), both with RPKI origin-validation state "not_found" Robtex IRR record. In plain terms: the network itself has never published its own signed route objects, and the routing system cannot cryptographically confirm who may originate these prefixes.

Registry label churn

One of the more revealing details is how the network's owner name keeps changing depending on which mirror you read, while the owner identifier stays the same. Hurricane Electric and IPinfo show "GMAES TELECOM LTDA EM RECUPERACAO JUDICIAL" IPinfo AS record; bgp.tools shows "GMAES TELECOM LTDA ME", with its embedded whois extract dated 5 May 2024 bgp.tools record; CIDR Report shows the AS as "AI BRAZIL TECHNOLOGIES & DATACENTER LTDA" CIDR Report, as above. One tax identifier, at least three display names across public mirrors — including the AI Brazil brand name on the network object itself. The underlying LACNIC/NIC.BR record ties the aut-num to owner GMAES TELECOM LTDA EM RECUPERACAO JUDICIAL, ownerid 15.644.251/0001-86, responsible CESAR ROBERTO SILVA PETRELLA, created 1 March 2018, last changed 25 September 2020, with inetnum blocks 45.232.28.0/22 and 2804:4a74::/32; the contact handle GMFSI61 (Gessica Maes Ferreira Silva, an e-mail on aibrazil.net.br) was created 19 October 2023 and changed 4 August 2026 IPIP.NET whois mirror. That August 2026 contact change is the most recent dated movement in the network record examined for this report — a registry-contact update, not a routing or infrastructure change.

The contract ledger: what the business actually sells

The verifiable commercial activity of the brand entity is municipal procurement. In 2026 alone, the record includes: a cloud collaboration with Pomerode, Santa Catarina, at R$450,900 (13 March 2026); corporate e-mail SaaS for Dois Vizinhos, Paraná, at R$24,490 for 350 licenses (8 May 2026); cloud storage for Ilhabela Prev, São Paulo, at R$1,314 (31 July 2026); and a first amendment to Pouso Redondo, Santa Catarina, Contract 85/2025 (25 August 2026) BTW follow-up report, 28 September 2026. The earliest operating trace found in public procurement is older: on 5 August 2025, Milagres, Ceará, contracted AI.BRAZIL TECHNOLOGIES & DATACENTER LTDA (CNPJ 45.908.107/0001-70) for R$6,000 to host an e-SUS health-system server in the cloud BTW case file.

These are real contracts with real municipal clients, and nothing in this report questions their validity. What they are not is datacenter capacity sales. They are hosting, e-mail and storage services — the classic profile of a small SaaS reseller — with values ranging from four figures to under half a million reais. The award notices reviewed do not disambiguate which of the two CNPJs signed, a gap the 28 September BTW report also flagged.

A sanction on the network-owning CNPJ

The federal supplier registry adds an element none of the prior coverage emphasized: the SICAF record for CNPJ 15.644.251/0001-86 (razão social GMAES TELECOM LTDA, nome fantasia G20 DATACENTER & INTERNET) lists a temporary-supplier-suspension sanction under Lei 8.666/93, article 87, item III — for total or partial non-execution of a contract — sanctioned by the Conselho Federal de Medicina Veterinária (CFMV), UASG 389185, process 1863/2020, contract CFMV 01/2021 BTW follow-up report citing SICAF. The sanction period was truncated in the retained snapshot, so only the sanction type, sanctioning body and process identifiers are claimed here. A company that owns the network behind an "AI datacenter" brand being recorded as sanctioned for contract non-execution is a fact municipal buyers would reasonably want to weigh.

What an AI datacenter would have to show

For the "AI datacenter" label to become a description, the public record would need to change in specific, checkable ways: new prefixes or a second upstream and downstream visibility in routing tables; RPKI route objects published under the operator's own identity rather than third-party proxies; a LACNIC or NIC.BR resource transfer or allocation reflecting expanded address need; utility, environmental-licensing or construction records in Santa Catarina tied to either CNPJ; or procurement notices on the buying side — a hyperscaler, GPU distributor or colocation tenant — naming either company as supplier of compute.

As of 1 October 2026, none of these signals appears in the sources examined.

Method and evidence boundaries

This report rests on routing mirrors (Hurricane Electric, CIDR Report, bgp.tools, IPinfo, IPIP.NET, Robtex), corporate registry mirrors (GuiaPJ, MonitorCNPJ), and BTW's prior case file and follow-up, all retrieved 1 October 2026. Four additional documents were retrieved into snapshots but their content could not be inspected within this reporting cycle: a TJAM procurement suspension file TJAM file, not inspected in this cycle, a PRF DOU extract PRF DOU extract, not inspected in this cycle, an FBN payment schedule FBN payment schedule, not inspected in this cycle, and a JUESC judicial-recovery report list JUESC recovery-report list, not inspected in this cycle. No claim in this report rests on those four documents. Routing-mirror pages were read through indexed excerpts on partly dynamic pages; RPKI state and propagation tables beyond what the mirrors render could not be confirmed. The judicial-recovery stage of CNPJ 15.644.251/0001-86 is not established at court-record level by these sources.

The conclusion is correspondingly narrow: the name says AI datacenter; the records say municipal SaaS reseller on a one-prefix network owned by a company in judicial recovery with a federal suspension sanction on file. Distance between label and evidence, measured, not asserted.
