Unclassified LACNIC
Summary
Embrapa (Empresa Brasileira de Pesquisa Agropecuária)
research government legacy
AS11097 is Embrapa, the Empresa Brasileira de Pesquisa Agropecuária — the Brazilian Agricultural Research Corporation, a state-owned research enterprise linked to Brazil's agriculture ministry and one of the world's largest tropical-agriculture research organisations. Every sampled reverse-DNS name sits under embrapa.br, so the space it announces is its own.
What it's used for
The corporation's research network. The AS announces 6 IPv4 prefixes (~17,664 addresses) — dominated by a single 200.202.128.0/18 — plus 6 IPv6 prefixes from Brazil's 2801:80::/32 LACNIC space, with 5 observed neighbours. A handful of upstreams and a large contiguous block is the shape of an institution consuming connectivity for its own sites, not one selling it.
Notable
The reverse DNS is a map of Embrapa's decentralised structure. Hostnames carry the unit code of the research centre they belong to: cnptia.embrapa.br (Informática Agropecuária, Campinas), cnpdia.embrapa.br (Instrumentação Agropecuária, São Carlos), cnpm.embrapa.br (Monitoramento por Satélite) and cppse.embrapa.br (Pecuária Sudeste). Embrapa runs dozens of such centres across Brazil, and the AS is the common internet edge stitching them together — named hosts like achernar, aion and elantra are individual servers, not subscriber pools.
Interesting
The prefix registrants come back as bare LACNIC/NIC.br numeric identifiers rather than names, which is normal for Brazilian registrations and is not the "unrelated third-party registrant" pattern that flags leased address space. The rDNS settles it: first-party names on every block, which is what a real operator holding its own inventory looks like.

Reputation
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: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
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.
