Summary

Petrobras

Brazil · AI-generated

business energy enterprise brazil

AS23074 is operated by Petrobras, the Brazilian state-owned petroleum and natural gas company.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the uniform netname 200219 across all listed prefixes and the registrant PETROLEO BRASILEIRO S.A. - PETROBRAS.
  • The AS announces 65536 IPv4 addresses across 22 prefixes and 17 IPv6 prefixes, with 35 observed neighbours; this ratio of moderate address space against a significant number of peers indicates a large-scale enterprise network with substantial transit and peering requirements.

Notable

  • All registrants in the evidence pack agree with the announcer, consistently listing PETROLEO BRASILEIRO S.A. - PETROBRAS.
  • The address inventory is finely subdivided within the 164.85.0.0/16 range, including a large /17 block and numerous /20, /21, /22, and /24 prefixes, reflecting site-by-site segmentation typical of a major corporate estate.
  • The network is identified as an Enterprise in PeeringDB, consistent with its role as the primary network for a major industrial corporation.

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 1,779 prefixes, as published 2026-10-22. 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.
