Summary

Controladoria-Geral da União

Brazil · AI-generated

government federal audit brazil

AS61572 is held by Controladoria-Geral da União (CGU), the Comptroller General of the Union, a branch of the Brazilian federal government.

What it's used for

  • The address space is registered under the netname 253177 with registrant CONTROLADORIA-GERAL DA UNIÃO, indicating internal government infrastructure.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with 3 observed neighbours, consistent with a small, self-contained institutional network rather than a transit or access provider.
  • Traffic from this AS consists of internal government systems, administrative endpoints, and audit-related services operated by the Brazilian federal oversight body.

Notable

  • Both announced IPv4 prefixes share the same netname 253177 and registrant CONTROLADORIA-GERAL DA UNIÃO, matching the AS holder exactly.
  • The address inventory is compact, comprising two contiguous IPv4 blocks (138.117.132.0/23 and 138.117.134.0/24) and two IPv6 prefixes, reflecting a single-site or limited multi-site government deployment.

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: 436 networks and 1,771 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.
