Brazil · AI-generated

isp residential brazil regional

AS28178 is operated by NWI Telecom, formerly known as Networld Provedor e Servicos de Internet Ltda.

What it's used for

  • The address space carries residential and small business internet access, evidenced by reverse DNS entries such as servflorestalnetwork26.nwi.com.br and nwi-telecom-255.87.85.189.nwi.com.br.
  • The AS announces 8192 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 18 observed neighbours; this ratio of address space to peering partners is consistent with a regional access provider rather than a transit carrier.

Notable

  • The RDAP registrants for both announced IPv4 prefixes (177.75.0.0/20 and 189.85.80.0/20) are listed as Networld Provedor e Servicos de Internet Ltda, matching the registry holder name.
  • Secondary sources identify the operator as NWI Telecom (aka Networld Telecomunicações do Brasil LTDA), indicating a corporate rename from the original Networld Provedor entity.
  • The inventory consists of two /20 IPv4 blocks and a single /32 IPv6 prefix, all located in Brazil.

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 1,851 prefixes, as published 2026-10-29. 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.
