Summary
Atualtek Telecom
isp residential brazil telecom
AS52560 is operated by Atualtek Telecom (registered as ATK Telecomunicacoes Ltda.).
What it's used for
- The address space carries residential and small business internet access, evidenced by reverse DNS entries pointing to
atualtektelecom.com.br(e.g.,146-254.atualtektelecom.com.br). - The AS announces 3 IPv4 prefixes totaling 3072 addresses and 1 IPv6 prefix, while maintaining 21 observed routing neighbours. This ratio of modest address inventory against a significant number of peering partners indicates a regional access provider aggregating traffic for end-users.
- Traffic originates from subscriber connections served by Atualtek Telecom, a Brazilian telecommunications company providing internet and telephony services.
Notable
- All three announced IPv4 prefixes share the same registrant, ATK Telecomunicacoes Ltda., confirming consistent ownership of the address space.
- The operator is identified in peering databases as Atualtek Telecom, a regional Network Service Provider (NSP) in Brazil.
- The inventory consists of three distinct /22 blocks in the 168.0.144.0, 177.86.68.0, and 186.235.92.0 ranges, alongside 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 1,782 prefixes, as published 2026-10-16. 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.
