AS11284 Nucleo de Inf. e Coord. do Ponto BR - NIC.

AS11284 belongs to NIC.br, the Brazilian body that runs the .br domain registry (Registro.br), the national CERT (CERT.br) and the IX.br exchange-point programme. RIS sees a small but very well-connected network: 3 IPv4 prefixes, 512 addresses, 3 IPv6 prefixes, and 50 observed neighbours.

What it's used for

NIC.br's own critical internet infrastructure, not customer traffic. The address inventory is tiny — half a /23 of IPv4 — while the neighbour count is fifty. That ratio is the tell: no eyeball or enterprise network of 512 addresses peers with fifty other autonomous systems. It is the signature of service infrastructure that wants to be reachable from everywhere, peered openly across Brazil's exchange fabric so that queries reach it in as few hops as possible. PeeringDB lists this network under the name NIC.BR c.dns.br, which is consistent with authoritative DNS for the .br zone being among what it carries.

Notable

All three IPv4 prefixes (200.192.232.0/23 and its two constituent /24s) and the IPv6 space (2001:12f8:a::/47 and /48s beneath it) are registered directly to Núcleo de Inf. e Coord. do Ponto BR — NIC.BR. Holder, registrant and announcer are the same organisation throughout. The /23-plus-covered-/24s pattern is deliberate route disaggregation, which is standard practice for anycast and for infrastructure that must stay reachable when a more-specific is withdrawn.

Interesting

NIC.br is not a government agency and not a commercial provider, and it does not fit either box cleanly: it is the executive arm of Brazil's multistakeholder internet steering committee, funded by domain registrations. Classifying the space by what it carries — public-good servers rather than subscribers, offices or leased capacity — is the honest reading, and that is why a network this small shows up at so many peering points.
