Summary
Zamix
isp residential cable dsl
The AS handle AS28171 is held by S. O. do Brasil Telecomunicacoes LTDA ME, operating under the brand Zamix.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to
zamix.com.br(e.g.,179-107-151-254.zamix.com.br). - The AS announces 21,504 IPv4 addresses across 5 prefixes and 27 IPv6 prefixes, while maintaining 34 observed neighbours. This ratio of moderate address space to a significant number of peering partners indicates a regional access provider rather than a large-scale transit carrier.
Notable
- All available RDAP registrants for the announced prefixes match the AS holder, S. O. do Brasil Telecomunicacoes LTDA ME, with netnames such as
229588and171215. - The operator is also known as SuperOnda, reflecting its historical identity or alternative branding in the Brazilian market.
- The inventory consists of five distinct IPv4 blocks, including two /19s and two /21s, alongside a substantial IPv6 allocation under the
2804:d84::/47range.

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 1,783 prefixes, as published 2026-10-17. 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.
