About this network

AS53196 is operated by NetSTAR Soluções.

What it's used for

• The address space carries residential and business internet access, evidenced by reverse DNS entries pointing to as53196.mg.netstar.com.br and registrant netnames such as 236019, 285569, and 149750.
• The AS announces 4096 IPv4 addresses across 6 prefixes and 17 IPv6 prefixes, while maintaining 31 observed neighbours; this ratio of moderate address inventory to a significant number of peering partners indicates a regional access provider rather than a transit hub.
• Traffic from this network consists of subscriber eyeballs for cable and DSL internet services in the Minas Gerais region of Brazil.

Notable

• All registrants for the announced prefixes are listed as NETSTAR SOLUÇÕES LTDA, which aligns directly with the AS holder name.
• The address inventory is composed of several /22 and /24 blocks in the 131.100, 170.231, and 186.232 ranges, along with a large IPv6 allocation under 2804:1d1c::/40.
