About this network

A small network belonging to the body that runs Brazil's internet registry and exchange points.

What it's used for

• Registry and coordination infrastructure. 512 addresses in one /23, one IPv6 /47, 26 observed BGP neighbours.

Notable

• 26 neighbours against 512 addresses. That ratio is the whole story: this network is interconnected far out of proportion to its size, which is what happens when the organisation running it is present at the exchange points rather than buying transit.
• The IPv4 block is 200.229.248.0/23, inside the 200.0.0.0/8 range LACNIC administers.
• The IPv6 announcement is a /47 out of 2001:12f8::/32.

Interesting

• NIC.br is the operational arm of Brazil's internet steering committee. It runs the .br domain, the country's address registry, its CERT, and IX.br — which by participant count and traffic is among the largest exchange point systems anywhere, spread across dozens of Brazilian cities rather than concentrated in one building.
• The organisation that coordinates all of that announces two /24s' worth of addresses. Its significance is in the number of networks it touches, and the routing data shows that directly: an address count that says nothing and a neighbour count that says everything.
