Residential APNIC
Summary
Entrenanet
isp residential regional brazil
AS53238 is operated by Chapeco Tecnologia em Telecomunicacoes Ltda., known commercially as Entrenanet.
What it's used for
- The address space carries residential and business broadband traffic, evidenced by reverse DNS entries such as
entrenanet--191-5-180-0.enn.net.brandserver11.hdrserver.com.br. - The AS announces 7168 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 36 observed neighbours; this ratio of moderate address space to a significant number of peering partners indicates a regional access provider rather than a large transit carrier.
- Traffic from this network consists of subscriber eyeballs and local business endpoints in the Chapecó region of Santa Catarina, Brazil, served via cable and DSL infrastructure.
Notable
- All registrants for the announced prefixes are listed as Chapeco Tecnologia em Telecomunicações Ltda., matching the AS holder.
- The address inventory is composed of a single /20 block and four smaller /22 and /23 blocks, 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: 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.
