About this network

AS61828 is operated by Netwise Informatica Ltda, a regional internet service provider based in Minas Gerais, Brazil.

What it's used for

• The address space carries residential and business customer traffic, evidenced by reverse DNS entries such as 170-150-133-0.netwise.com.br and 201-222-29-0.netwise.com.br.
• The AS announces 2048 IPv4 addresses across 2 prefixes and 10 IPv6 prefixes, while maintaining 35 observed neighbours; this ratio of modest address inventory against a significant number of peering partners indicates a regional access network rather than a major transit provider.
• Traffic from this AS consists of subscriber eyeballs and local business endpoints served via cable and DSL infrastructure in the Lagoa da Prata region.

• The address inventory is compact, consisting of two /22 blocks in IPv4 and a contiguous set of IPv6 prefixes under the 2804:19f4::/33 range.
