Unclassified LACNIC NSP
Summary
American Tower do Brasil
telecom infrastructure brazil tower
AS23106 is operated by American Tower do Brasil.
What it's used for
- The address space carries infrastructure for a telecommunications and tower company, evidenced by the registrant name
AMERICAN TOWER DO BRASIL-COMUNICAÇÂO MULTIMÍDIA LTand reverse DNS entries likeBHE191254.CORP.atcmultimidia.com.brandc88b9000.virtua.com.br. - The AS announces 167936 IPv4 addresses across 11 prefixes and 1 IPv6 prefix, while maintaining 286 observed neighbours; this high neighbour count relative to the address inventory suggests a role in transit or interconnection rather than a pure access network.
Notable
- All registrants for the announced prefixes match the announcer, consistently listed as
AMERICAN TOWER DO BRASIL-COMUNICAÇÂO MULTIMÍDIA LT. - The address inventory is finely subdivided into multiple /18, /19, /20, and /21 blocks, indicating a segmented corporate estate rather than a single contiguous allocation.

Reputation
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
