Summary

Brazil · AI-generated

residential isp brazil

AS52893 is operated by F1 Solutions Datacenter E Telecomunicacoes Ltda.

What it's used for

  • The address space carries dynamic subscriber traffic, evidenced by reverse DNS entries such as 131-161-169-0.dynamic.f1solutions.com.br and 131-161-170-254.dynamic.f1solutions.com.br.
  • The AS announces 5,120 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 4 observed routing neighbours.
  • This ratio of address space to neighbours indicates an access network providing connectivity to end-users rather than a transit provider.

Notable

  • Both announced IPv4 prefixes (177.37.48.0/20 and 131.161.168.0/22) list F1 SOLUTIONS DATACENTER E TELECOMUNICACOES LTDA as the registrant, matching the AS holder.
  • The inventory consists of two distinct IPv4 blocks and a single IPv6 /34, representing a modest footprint typical of a regional Brazilian ISP.

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.
