isp residential cable brazil

Fibron Telecom is operated by Fibron Telecom, a regional cable and DSL provider in Brazil.

What it's used for

  • The address space carries residential customer traffic, evidenced by reverse DNS entries such as clt-home-0.114.185.177.fibron.com.br and clt-home-255.115.185.177.fibron.br.
  • The AS announces 4096 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 26 observed neighbours; this ratio of modest address space against a moderate neighbour count is consistent with an access network providing last-mile connectivity.
  • Traffic from this AS consists of subscriber eyeballs for residential internet access, including web browsing, streaming, and VoIP, delivered via cable and DSL infrastructure.

Notable

  • Registrants for both announced prefixes (177.185.112.0/21 and 187.86.24.0/21) are listed as Fibron Telecom, matching the AS holder.
  • The operator is also known as Tecnowireless Telecom, a name change or alias reflected in peering databases.
  • The inventory comprises two /21 IPv4 blocks and a single /32 IPv6 prefix, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
