.def.br domains list

What is .def.br TLD

The .def.br TLD denotes a structured namespace segment within Brazil’s .br country‑code domain, used for clearly delineated institutional purposes. In practice, registrations occur at the third level, and we monitor both .def.br domains and .def.br websites as part of our global index. To quantify current footprint, we record 17 active registrations, with 14 live hosts responding on the web and 14 configured with DNS. Activity spans 2 countries when considering name servers, hosting, and registrant footprints, reflecting a focused but internationally reachable presence. Our role is to map this niche of the .br hierarchy with consistent, comparable indicators across time and networks. Download .def.br domain datasets from webatla.

History and key features of .def.br TLD

Historically, Brazil’s .br registry has organized registrations under defined second‑level categories, enabling third‑level names that align with institutional missions; .def.br follows this hierarchical model. We analyze .def.br domains and .def.br websites through signals such as DNS readiness, HTTPS adoption, hosting geography, and organizational consistency. Recent activity has been stable: 0 new discoveries last week and 0 in December 2025 across the prior month, suggesting low churn and controlled issuance. Today, our index shows 14 domains with DNS from 17 total, and 14 live properties accessible on the open web. These features indicate a constrained, policy‑guided namespace with predictable behavior and measurable exposure. Download .def.br domain datasets from webatla for time‑series and entity mapping.

Why and who choose the .def.br domain

Organizations adopt .def.br when they require Brazil‑aligned identity, formal categorization, and predictable governance. In our observations, .def.br domains concentrate among entities operating within regulated or public‑interest contexts, with .def.br websites emphasizing clarity of mission, security controls, and conservative change windows. Empirically, 14 live sites against 17 registrations, plus 14 DNS‑enabled names, indicate purposeful deployment rather than speculative holdings. Operational touchpoints span 2 countries through hosting, networks, or registrant presence, supporting cross‑border collaboration while signaling Brazilian attribution. For teams evaluating risk, compliance, brand protection, or supplier discovery, this namespace provides consistent heuristics for classification and monitoring across time and infrastructure.
