Residential LACNIC
Summary
Linca Telecomunicações
isp residential cable regional
AS28223 is operated by Linca Telecomunicações LTDA.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to
linca.net.br(e.g.,189.126.33.0.linca.net.br). - The AS announces 1792 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a regional access provider rather than a transit hub.
Notable
- All registrants for the announced prefixes are listed as
Linca Telecomunicações LTDA, matching the AS holder. - The inventory consists of three contiguous IPv4 blocks within the 189.126.32.0/22 range, suggesting a consolidated internal estate for a single regional operator.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
