government judiciary brazil
SUPREMO TRIBUNAL FEDERAL is the autonomous system for the Supremo Tribunal Federal, the Supreme Federal Court of Brazil.
What it's used for
- The address space is registered under the netname
559097with the registrantSUPREMO TRIBUNAL FEDERAL, indicating a dedicated internal network for the court's operations. - The AS announces 1024 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, a ratio characteristic of a small, self-contained institutional network rather than a transit or access provider.
- Traffic from this AS consists of internal communications, web services, and administrative endpoints for the Brazilian Supreme Court, supporting its role as the highest court in the country.
Notable
- The registrants for both announced IPv4 prefixes match the AS holder,
SUPREMO TRIBUNAL FEDERAL, confirming consistent ownership. - The address inventory consists of two contiguous /23 blocks in the 201.49.0.0/16 range and a single /44 IPv6 prefix, forming a compact and well-defined estate for a government institution.

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.
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.
