Unclassified APNIC
Summary
SBS-NET Telecomunicações
isp residential cable dsl
AS52539 is operated by SBS-NET Telecomunicações LTDA ME.
What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries pointing to
g6internet.com.br(e.g.,179-106-183-255.g6internet.com.br). - The AS announces 4096 IPv4 addresses within a single /20 prefix (179.106.176.0/20) and 8 IPv6 prefixes, while maintaining only 1 observed routing neighbour.
- This high address-to-neighbour ratio indicates an access network providing last-mile connectivity to end-users rather than a transit provider.
Notable
- The RDAP registrant for the announced prefix matches the AS holder, identified as SBS-NET TELECOMUNICACOES LTDA ME with netname 203649.
- The address inventory consists of one contiguous IPv4 block and a set of hierarchical IPv6 allocations, typical of a regional ISP managing its own customer base.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-23, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,779 prefixes, as published 2026-10-24. 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.
