Summary

Brasil Site Informatica

Brazil · AI-generated

hosting business brazil

AS53243 is operated by Brasil Site Informatica LTDA.

What it's used for

  • The address space carries hosting and web services, evidenced by reverse DNS entries such as rdns64.panfletovirtual.com.br, antispam.nuvemprofissional.com.br, hostmail.certahost.com.br, and host250-254.playunix.com.br.
  • The AS announces 4,352 IPv4 addresses across 4 prefixes and 17 IPv6 prefixes, while maintaining 32 observed neighbours. This ratio of moderate address space to a significant number of peering partners suggests a role focused on hosting and business connectivity rather than pure transit or residential access.
  • Traffic from this AS consists of web hosting, mail servers, and API endpoints for small to medium-sized Brazilian businesses, consistent with the operator's identity as an IT services and hosting provider.

Notable

  • Registrants for the available prefixes (177.53.140.0/22, 190.89.248.0/22, 201.182.40.0/24) all match the announcer, Brasil Site Informatica LTDA, with netnames 217412, 479850, and 553759 respectively.
  • The inventory is composed of four distinct IPv4 blocks and a large, contiguous IPv6 allocation under 2804:11a4::/33, indicating a stable and self-contained address estate.

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 1,783 prefixes, as published 2026-10-17. 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.
