Summary
NIC.br
research enterprise legacy
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 the200.0.0.0/8range LACNIC administers. - The IPv6 announcement is a
/47out of2001:12f8::/32.
Interesting
- NIC.br is the operational arm of Brazil's internet steering committee. It runs the
.brdomain, 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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
