Autonomous system
AS11284 Nucleo de Inf. e Coord. do Ponto BR - NIC.
Unclassified LACNIC
Summary
NIC.br (Núcleo de Informação e Coordenação do Ponto BR)
research enterprise legacy
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which is standard practice for anycast and for infrastructure that must stay reachable when a more-specific is withdrawn.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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
