Summary

Fundação Universidade de Caxias do Sul

Brazil · AI-generated

education university brazil

AS22819 is operated by Fundação Universidade de Caxias do Sul.

What it's used for

  • The address space is registered to the university, with netnames 33237 and 53422 assigned to the two announced IPv4 blocks.
  • The AS announces 8192 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours, a ratio consistent with an institutional access network rather than a transit provider.

Notable

  • Both RDAP registrants match the AS holder, confirming the space is directly owned by the university.
  • The inventory consists of two /20 IPv4 blocks and a single /48 IPv6 prefix, representing a modest, self-contained estate typical of a large academic institution.

Reputation

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
