Residential LACNIC
Summary
Arganet
isp cable dsl regional
AS28254 is operated by Arganet Comunicacao e Monitoramento Digital Ltda.
What it's used for
- The address space carries residential and business access traffic, consistent with the operator's classification as a Cable/DSL/ISP.
- The AS announces 6144 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 28 observed neighbours. This ratio of moderate address space against a significant number of peering partners suggests a regional access provider with substantial upstream and peering connectivity.
Notable
- Both announced IPv4 prefixes, 187.16.128.0/20 and 177.71.16.0/21, list Arganet Comunicacao e Monitoramento Digital Ltda as the registrant, confirming direct ownership of the address space.
- The inventory consists of two distinct IPv4 blocks and a single /32 IPv6 prefix, indicating a focused regional footprint rather than a large national or international carrier.

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: 442 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.
