Brazil’s Unified Government Portal Now Runs on IPv6 — A Milestone for the Country’s Internet

Last weekend, Brazil reached a historic milestone: the unified government portal www.gov.br became accessible over IPv6. And just a few minutes ago, the AAAA record for the root domain gov.br itself was also activated, further consolidating this important step in Brazil’s Internet modernization process.
This step, led by teams at Serpro (the Federal Data Processing Service) and supported by the Ministry of Management and Innovation in Public Services (MGI), marks a significant advance in the modernization of the country’s digital infrastructure. It is the result of years of technical preparation and commitment to future-proof connectivity.
What gov.br Is, and What It Isn’t
The gov.br domain is not a single website, but a unified and aggregating portal that centralizes access to hundreds of government services and institutions. It serves as the main gateway for citizens to interact with public services, but many of these services are actually hosted on separate systems and URLs, often managed by different agencies.
That means the activation of IPv6 on the portal itself does not yet imply that all underlying services and subdomains are IPv6-enabled. Still, the change at the core of the gov.br infrastructure has enormous symbolic and practical importance. It sets the example and establishes the baseline for the broader transition across the federal ecosystem.
Why It Matters
Moving the main federal portal to IPv6 signals a strategic commitment to the future of the Internet in Brazil. IPv6 allows for end-to-end connectivity without NAT, improving performance, resilience, and traceability, what is essential for security operations and better user experience. It also enables clearer identification of devices and faster responses to security incidents.
From a citizen’s point of view, the impact may initially seem invisible, but over time it translates into more reliable access, better connectivity, and enhanced protection.

A Step That Inspires Others
Even though this is just one step, it’s a big one. It demonstrates technical readiness and coordination within the federal government, and sends a clear message to other sectors: it’s time to accelerate.
Brazil already ranks among the top countries in IPv6 adoption, thanks to consistent work from the technical community, ISPs, and organizations like NIC.br and CGI.br. Now, with gov.br joining in, the momentum toward full IPv6 deployment, including in banks, e-commerce, and private enterprises, is likely to grow stronger.
