Who is PeeringDB?
PeeringDB is a nonprofit, community-maintained database of self-reported interconnection data covering autonomous systems, internet exchange points, and colocation facilities, used by network operators to identify and coordinate peering relationships.
- Publicly accessible registry of network peering policies and contact information
- Records of internet exchange points and the networks connected to each exchange
- Listings of colocation and data center facilities with interconnection details
- Public REST API returning structured JSON for programmatic queries
- Community-maintained records supporting interconnection coordination among network operators

More About PeeringDB
PeeringDB is operated by a nonprofit organization and publishes data contributed by network operators, internet exchange operators, and facility operators. Network teams use the database to identify potential peering partners, confirm technical and policy contacts, and review published peering policies before establishing interconnection sessions. Each participant maintains its own records, which are visible to others in the industry.
Enterprise and service provider environments that operate autonomous systems or consume transit services use the data during network design and vendor evaluation. Records typically include autonomous system numbers, network type, traffic profile, facility presence, and the internet exchanges where a network is connected. Infrastructure teams apply this information when planning multihomed connectivity, selecting exchange locations, and evaluating routing options within Border Gateway Protocol (BGP) architectures.
The database supports manual lookup through its web interface and programmatic access through a public REST API that returns structured JSON. Automation teams integrate these endpoints into peering workflows, route policy tooling, and capacity planning processes. Returned data can also feed configuration generation and network documentation.
Comparable solution categories include internet exchange directories, colocation facility catalogs, and internal network source of truth systems. PeeringDB differs from internal inventory tools because it is a shared, cross-organization registry whose records are contributed by the networks they describe. Its scope centers on interconnection data rather than operational telemetry or live routing state.
Accurate and current interconnection data affects latency, transit cost, and resilience decisions for participating networks. Current peering information shortens the time required to establish sessions and supports traffic exchange between networks. Directory positioning centers on interconnection data for network operators, internet exchange operators, and data center providers, in line with its focus on internet infrastructure coordination.
