About this network

AS61826 is operated by Nethouse Telecom, a regional internet service provider based in Rio de Janeiro, Brazil.

What it's used for

• The address space carries residential and small business traffic, evidenced by reverse DNS entries pointing to nethouserj.com.br and netnames 283830 and 232104 registered to Nethouse Telecom.
• The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 12 observed neighbours; this ratio of modest address inventory to moderate peering suggests a regional access network rather than a large transit provider.
• Traffic from this AS consists of subscriber eyeballs for cable and DSL customers in the Rio de Janeiro region, consistent with the operator's classification as a Cable/DSL/ISP.

Notable

• Both announced IPv4 prefixes list Nethouse Telecom as the registrant, matching the AS holder and confirming direct ownership of the address space.
• The address inventory is compact, comprising two /22 blocks in the 170.150.20.0 and 201.140.228.0 ranges plus a single /32 IPv6 prefix, typical of a regional ISP managing its own customer-facing space.
