Peering DB

PeeringDB is a freely available, community-maintained database of internet exchange points, networks, and peering facilities that documents the interconnection infrastructure of the internet. It contains verified information about Autonomous Systems (networks), internet exchange points (IXPs), and the facilities where network operators colocate equipment and establish peering relationships.

For OSINT investigators working on advanced network infrastructure investigations, PeeringDB provides intelligence about how networks interconnect — information that is not available from standard WHOIS or routing databases. Understanding where a network peers, what facilities its equipment is in, and what other networks it interconnects with adds a layer of physical and operational infrastructure intelligence.

ASN investigation through PeeringDB reveals which physical data centers an Autonomous System operates in, where it has internet exchange point presence, what peering policy it follows, and contact information for the network operations team. This data is valuable for law enforcement investigations requiring physical location intelligence for network operators.

For infrastructure attribution, PeeringDB can confirm whether a specific network operates in specific facilities — corroborating claims about data center locations or revealing undisclosed network presence. Networks that operate in specific IXPs and colocation facilities can be physically located to specific buildings in specific cities.

Internet exchange point data from PeeringDB is valuable for understanding traffic routing patterns. If a suspect network peers at a specific IXP, traffic to or from that network may be accessible through monitoring at that exchange point — intelligence relevant to lawful interception planning.

Corporate network investigations may use PeeringDB to understand whether a target organization operates their own autonomous system and where their network infrastructure is physically located. Large enterprises with significant internet presence frequently appear in PeeringDB.

PeeringDB data is voluntarily submitted by network operators and is therefore more complete for major, professionally-operated networks than for small or less cooperative operators.

Document ASN numbers, facilities, IXP presence, and contact information retrieved from PeeringDB with query timestamps.
