Summary
Net Rosas Telecomunicacoes
isp residential cable regional
AS28219 is operated by Net Rosas Telecomunicacoes Ltda., a regional telecommunications provider in Brazil.
What it's used for
- The address space carries residential user traffic, evidenced by reverse DNS entries like
user.0-228-236-186.users.net-rosas.com.branduser.255-231-236-186.users.net-rosas.com.br. - The AS announces 8192 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 27 observed neighbours, indicating a role as an access or eyeball network rather than a transit provider.
Notable
- Registrants for both announced IPv4 prefixes (
186.236.224.0/20and189.124.16.0/20) match the AS holder, Net Rosas Telecomunicações Ltda. - The address inventory consists of two /20 blocks in the IPv4 space and a single /32 in IPv6, typical for a regional ISP managing customer-facing address space.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
