Summary

Brazil · AI-generated

isp residential brazil small

ESTREITONET LTDA is the AS handle for Estreitonet, a telecommunications provider based in Estreito, Maranhão, Brazil.

What it's used for

  • The address space is registered under the netname 191960 with registrant ESTREITONET LTDA, indicating a direct corporate holding of the IP inventory.
  • The network announces 1024 IPv4 addresses within a single /22 prefix (177.53.116.0/22) and one IPv6 prefix (2804:ba8::/32), while maintaining only 1 observed routing neighbour.
  • This high address-to-neighbour ratio characterizes the AS as an access or eyeball network, where the operator provides last-mile connectivity to end-users rather than serving as a transit provider for other networks.

Notable

  • The RDAP registrant ESTREITONET LTDA matches the AS holder name exactly, confirming consistent ownership of the announced address space.
  • The inventory consists of a single contiguous IPv4 block and a single IPv6 prefix, representing a compact and self-contained address estate typical of a regional 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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
