About this network

INFOLINE BANDA LARGA is the AS handle for Infoline Banda Larga, a regional internet service provider based in Campos dos Goytacazes, Rio de Janeiro.

What it's used for

• The address space carries residential and business broadband traffic, evidenced by reverse DNS entries pointing to client.infolinebandalarga.com.br across all three announced IPv4 prefixes.
• The AS announces 2,560 IPv4 addresses and 1 IPv6 prefix, maintaining 28 observed neighbours; this ratio of modest address space against a significant number of peering partners indicates an access network distributing traffic to end-users rather than a transit provider.
• Traffic from this AS consists of subscriber eyeballs for residential and corporate internet plans, as the operator provides wired telecommunications services to local clients.
