About this network

What it's used for

• The address space is registered under the netname 179995 for both announced IPv4 prefixes, indicating a single administrative entity.
• The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 27 observed neighbours. This ratio of moderate address space to a significant number of peering partners suggests a regional access provider or small ISP rather than a large transit carrier.
• Traffic from this AS consists of subscriber eyeballs and local internet access services, consistent with the operator's business as a telecommunications and informatics company serving specific regions in Brazil.

Notable

• The address inventory is compact, comprising two contiguous IPv4 blocks and one IPv6 /36, typical of a regional ISP managing local customer allocations.
