Summary

cable isp residential brazil
AS28220 is operated by Alares Internet, a regional cable and DSL provider in Brazil.
What it's used for
- The address space carries residential cable access, with reverse DNS entries consistently following the pattern
cable.cabotelecom.com.br(e.g.,177-89-32-0.cable.cabotelecom.com.br). - The AS announces 307,712 IPv4 addresses across 109 prefixes and 92 IPv6 prefixes, while maintaining 103 observed neighbours; this high address-to-neighbour ratio indicates an access network rather than a transit provider.
Notable
- All sampled registrants match the AS holder,
Alares Cabo Servicos de Telecomunicacoes S.A., with netnames such as229657,183680, and197876. - The inventory is dominated by large blocks in the 177.89.0.0/17 and 187.61.192.0/18 ranges, supplemented by numerous /19 and /20 prefixes across the 177, 179, 186, 187, and 189 blocks.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
