Residential AFRINIC Cable/DSL/ISP
Summary
PredialNet
residential isp cable dsl
AS28665 is operated by PredialNet Provedor de Internet Ltda.
What it's used for
- The address space carries residential broadband access, evidenced by reverse DNS entries such as
fttx-1771223254.usr.predialnet.com.brand189001141254.usr.predialnet.com.br, indicating FTTH and user-facing infrastructure. - The AS announces 28,672 IPv4 addresses across 18 prefixes and 1 IPv6 prefix, with 31 observed neighbours; this ratio of address volume to peering partners is consistent with a regional access provider rather than a transit carrier.
Notable
- All RDAP registrants for the largest prefixes are listed as
Predlink Rede de Telecomunicções Ltda, matching the AS holder name in the registry. - The address inventory is subdivided into multiple /21, /22, /23, and /24 blocks within the 177.12.0.0/16, 177.136.0.0/16, and 189.1.0.0/16 ranges, reflecting a finely segmented internal estate typical of a growing regional ISP.

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: 440 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.
