Summary

USCM - Comunicação Multimídia

Brazil · AI-generated

isp residential brazil access

USCM - COMUNICACAO MULTIMIDIA LTDA. is held by USCM - Comunicação Multimídia.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as 64-208-96-179.uscm.net.br and disaffected.mostlocals.com.
  • The AS announces 1792 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 29 observed neighbours; this ratio of modest address space against a significant number of peering partners indicates a regional access provider rather than a transit hub.
  • Traffic from this network consists of subscriber eyeballs and local business endpoints within Brazil, consistent with the operator's role as a communications provider.

Notable

  • All registrants for the announced prefixes match the announcer, with USCM - COMUNICACAO MULTIMIDIA LTDA. listed for 179.96.212.0/22, 179.96.210.0/23, and 179.96.208.0/24.
  • The inventory is compact, consisting of three contiguous IPv4 blocks within the 179.96.208.0/22 range and a single /32 IPv6 prefix.

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 1,771 prefixes, as published 2026-10-15. 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.
