isp residential cable dsl

The AS handle TSS SOFTWARE LTDA ME is held by TSS SOFTWARE LTDA, operating under the brand Conexão Internet.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as dyn-125-254.conexaointernet.com.br and dyn-170.0.146.254.conexaointernet.com.br.
  • The network announces 3,072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 4 observed neighbours, indicating a local access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for cable and DSL internet services in Brazil.

Notable

  • Registrants for both announced prefixes (177.85.120.0/21 and 170.0.144.0/22) are listed as TSS SOFTWARE LTDA, matching the AS holder.
  • The address inventory is compact, consisting of two distinct IPv4 blocks and a single IPv6 /32 prefix.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
