Summary

Fundação Educacional Severino Sombra

Brazil · AI-generated

education university brazil

FUNDACAO EDUCACIONAL SEVERINO SOMBRA is the autonomous system for Fundação Educacional Severino Sombra.

What it's used for

  • The address space carries the institutional network of a Brazilian university, as indicated by the registrant netname 232372 and the holder name.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with 2 observed neighbours, indicating a small, self-contained campus network rather than a transit or access provider.
  • Traffic from this AS consists of internal university operations, including administrative systems, research infrastructure, and student/staff connectivity within the campus.

Notable

  • The RDAP registrant FUNDAÇÃO EDUCACIONAL SEVERINO SOMBRA matches the AS holder exactly, confirming direct ownership of the address space.
  • The address inventory is minimal, consisting of a single /24 block and one /48 IPv6 prefix, typical for a private educational institution managing its own internal network.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
