Who is IX.br?
IX.br (Brazilian Internet Exchange) is the national Internet exchange point system for Brazil, providing shared infrastructure for IP traffic interconnection among networks operating in the country.
- Operation of Internet Exchange Points (IXP) in multiple Brazilian regions for multilateral peering among autonomous systems (network interconnection).
- Shared Ethernet switching infrastructure and route server services to enable BGP-based peering (IP networking).
- Support for content providers, ISPs, academic networks, and enterprise networks to exchange traffic locally in Brazil (interconnection services).
- Technical coordination, statistics, and documentation related to Brazilian interconnection traffic (network operations visibility).
- Collaboration with Network Interface Controller (NIC).br and the Brazilian Internet Steering Committee (CGI.br) in the management of Brazil’s Internet infrastructure (governance and infrastructure services).

More About IX.br
IX.br is the Brazilian Internet Exchange system that provides layer 2 Ethernet infrastructure and route server services to enable settlement-free or bilaterally negotiated IP traffic exchange among autonomous systems operating in Brazil. It is operated by NIC.br under the guidance of the Brazilian Internet Steering Committee (CGI.br) and is positioned as a neutral interconnection fabric for carriers, ISPs, content delivery networks, cloud providers, academic networks, and enterprise networks.
The platform is organized as a distributed set of IXP (IXPs) deployed in several metropolitan regions in Brazil. Each IXP typically provides one or more switching domains where participants connect via 1G, 10G, 100G, or higher-capacity Ethernet ports, depending on availability. Participants establish Border Gateway Protocol (BGP) sessions either bilaterally with other members or via IX.br route servers (routing control plane) to simplify multilateral peering. Traffic then flows at layer 2 within the IX.br switching fabric, allowing local exchange of IP packets without transiting upstream transit providers.
From an enterprise and institutional perspective, IX.br is used to improve latency and control bandwidth costs for traffic destined to Brazilian users and services. Content providers and CDNs use IX.br to reach broadband and mobile operators more directly, while ISPs and regional networks use it to access a broad set of content and cloud networks through a single physical interconnection point. Academic and research networks use the exchange fabric to interconnect with other research networks and service providers that operate in Brazil.
Architecturally, IX.br relies on standard Ethernet switching (data center networking) and BGP (routing protocol) for interconnection, similar to other IXP globally. The presence of route servers (routing mediation) reduces the need for a full mesh of BGP sessions among participants and simplifies peering policy management. IX.br also publishes traffic statistics and participant lists, which support capacity planning, network engineering, and traffic analysis for connected organizations.
In an enterprise IT directory or marketplace taxonomy, IX.br aligns with categories such as network interconnection services, IXP, carrier-neutral peering fabric, and Internet infrastructure coordination. It does not function as a transit provider; instead, it provides a shared switching and routing coordination environment through which participants can implement their own peering and Traffic Engineering (TE) policies. This role makes IX.br part of the underlying infrastructure that supports Internet connectivity, content delivery, and cloud access within Brazil.
