AS10954 SERVICO FEDERAL DE PROCESSAMENTO DE DADOS - SERPRO

AS10954 is Serviço Federal de Processamento de Dados (SERPRO), the Brazilian federal government's data-processing corporation. RIS observes 34 IPv4 prefixes covering 147,456 addresses, 8 IPv6 prefixes, and 34 observed neighbours. The sampled reverse DNS resolves under serpro.gov.br, confirming the space is used by SERPRO itself rather than reassigned to unrelated parties.

What it's used for

SERPRO is the state-owned IT services company that builds and runs the systems behind much of Brazil's federal administration, most visibly the tax authority's filing and collection platforms. The routed space is the delivery network for those systems: datacentre capacity, public-facing government services, and the federal agencies that consume them. A PTR such as dibm1.bsa.serpro.gov.br points at Brasília, which is where the organisation is headquartered.

Notable

The prefix set spans three separate ranges (161.148.0.0/16, 189.9.0.0/16 and part of 200.198.0.0), each announced both as an aggregate and broken down into /18s, /19s and smaller. That layering is deliberate: it lets the operator steer individual blocks across different paths while keeping a single covering route as a safety net if a more-specific is withdrawn.

Interesting

Thirty-four neighbours and a full IPv6 deployment across eight prefixes make this one of the better-connected government networks in Latin America. IPv6 is unusually well established in Brazil generally, and a federal service provider carrying real v6 in the global table is a reflection of that.
