AS19611 is operated by Associação Antônio Vieira - Unisinos.

What it's used for

  • The address space carries university infrastructure, evidenced by reverse DNS entries such as asav-95-254.unisinos.br and asav-183-254.unisinos.br.
  • The AS announces 69,632 IPv4 addresses across 17 prefixes and 1 IPv6 prefix, with 6 observed neighbours, indicating a self-contained institutional network rather than a transit provider.

Notable

  • All registrants in the RDAP data match the announcer, consistently listed as Associação Antônio Vieira - Unisinos.
  • The inventory is dominated by the 191.4.0.0/17 block, with smaller allocations in 200.188.160.0/21 and 200.188.168.0/22, reflecting a consolidated internal estate.

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 1,768 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.
