Summary

SAMM Tecnologia e Telecomunicacoes S.A

unknown · AI-generated

telecom brazil business

AS28330 is operated by SAMM Tecnologia e Telecomunicacoes S.A.

What it's used for

  • The address space is registered under netnames 517788, 517789, and 517790, all assigned to SAMM Tecnologia e Telecomunicacoes S.A.
  • The AS announces 9216 IPv4 addresses across 11 prefixes and 11 IPv6 prefixes, with only 1 observed neighbour, indicating a small-scale access or internal network rather than a transit provider.

Notable

  • All registrants in the RDAP data match the announcer, consistently listing SAMM Tecnologia e Telecomunicacoes S.A.
  • The inventory consists of finely subdivided blocks, including /21, /22, /23, and /24 prefixes, suggesting site-by-site segmentation within a corporate or regional telecom estate.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
