Summary
Fundação Oswaldo Cruz (Fiocruz)
research government science brazil
The AS handle FUNDACAO INSTITUTO OSWALDO CRUZ is held by Fundação Oswaldo Cruz (Fiocruz), a major Brazilian public research institution.
What it's used for
- The address space carries the institutional network of Fiocruz, a scientific institution for research and development in biological sciences located in Rio de Janeiro.
- The AS announces 65,536 IPv4 addresses across 41 prefixes, all within the 157.86.0.0/16 range, with only 5 observed routing neighbours, indicating a single-site or multi-site corporate estate rather than a transit or access network.
Notable
- All registrants in the RDAP data match the announcer, consistently listed as FUNDACAO INSTITUTO OSWALDO CRUZ with the netname 200212.
- The address inventory is finely subdivided into numerous /20, /21, /22, and /23 blocks, reflecting internal segmentation of the institution's network rather than external customer allocation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
6 upstream, 0 downstream and 6 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,782 prefixes, as published 2026-10-16. 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.
