isp residential cable brazil

CABONNET INTERNET LTDA is the AS handle for Cabonnet Internet, a Brazilian internet service provider.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS records pointing to cabonnet.com.br across all sampled prefixes.
  • The network announces 14,336 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a local access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local web/API endpoints for customers in the Presidente Prudente region of Brazil.

Notable

  • Registrants for the available prefixes (179.107.0.0/21, 187.87.64.0/21, 131.100.68.0/22, 168.195.236.0/22) all match the announcer, CABONNET INTERNET LTDA.

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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
