isp residential cable dsl

AS52540 is operated by H&F SOLUCOES TECNOLOGICAS LTDA, known commercially as Centranet.

What it's used for

  • The address space carries residential and small business subscriber traffic, evidenced by reverse DNS records pointing to host.centranet.com.br.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a local access provider rather than a transit carrier.
  • Traffic consists of end-user internet access via cable and DSL connections, consistent with the operator's classification as a Cable/DSL/ISP.

Notable

  • Registrants for both announced IPv4 prefixes (138.185.44.0/22 and 177.129.124.0/22) match the AS holder, H&F SOLUCOES TECNOLOGICAS LTDA.
  • The address inventory is compact, consisting of two /22 blocks and a single /32 IPv6 prefix, typical of a regional ISP managing its own customer base.

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 1,768 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.
