What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to
tri.net.br(e.g.,187-44-84-0.tri.net.br). - The AS announces 6144 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 10 observed neighbours. This ratio of address space to peering partners is consistent with a regional access provider rather than a transit carrier.
Notable
- All registrants for the announced prefixes (
187.44.80.0/20,138.255.140.0/22,177.105.252.0/22) are listed asTRI TELECOM LTDA, matching the AS holder. - The address inventory consists of three distinct IPv4 blocks and one IPv6 /32, all located in Brazil.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
