What is .ato.br TLD

.ato.br is a structured third‑level space within Brazil’s .br country-code top‑level domain, reserved by the Brazilian registry for specific registrant categories and naming policies. In practice, .ato.br domains identify entities that need a clearly scoped namespace under .br, while .ato.br websites are the live services resolving on that namespace. Using our global index, we currently observe 47 active registrations and 34 operational sites, distributed across 4 countries by hosting or registrant footprint. This makes the zone modest in size but measurable for compliance, outreach, and brand-protection monitoring. We maintain continuous telemetry on DNS, web content, and lifecycle events to keep visibility objective and comparable to other .br categories.

History and key features of .ato.br TLD

The .br registry operates a category-based structure where specialized second-level labels organize registrations; .ato.br participates in this model, providing a controlled namespace with predictable semantics. While exact policy details are set by the registry, the pattern favors clarity and segmentation across sectors, which benefits both .ato.br domains and .ato.br websites. From an operational standpoint, we see 34 of 47 domains publishing DNS records, indicating substantive configuration rather than parked inventory. Recent churn is limited: 0 new registrations last week and 1 in December 2025 month-over-month, suggesting a stable, low‑volume zone. These signals help security teams and analysts prioritize coverage, detect typosquatting risks, and benchmark adoption against other .br categories.

Why and who choose the .ato.br domain

Organizations operating in or serving Brazil select .ato.br to signal alignment with a structured .br naming convention and to partition services under a clearly scoped label. This can help compliance, discovery, and governance workflows for both .ato.br domains and .ato.br websites, where predictable taxonomy reduces ambiguity for users and crawlers. For due diligence, we track 47 active registrations, 34 live sites, and 4 countries of usage, letting teams assess exposure, vendor footprints, and infrastructure patterns. Combined with 34 configured zones, the namespace lends itself to targeted monitoring, certificate inventory, and threat hunting with minimal noise. Analysts, brand stewards, and public-interest researchers benefit from this clarity and manageable scale. Download .ato.br domain datasets from webatla to profile adopters and uses.
