About this network

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.
