Network Engineering APIs. Internet Intelligence.

This API extends the ASN Info API with two additional data sets: the full list of networks the AS receives traffic from, and the networks it transits traffic to. It also returns the geographic coordinates of the AS's most active operating region, where available, derived from BigDataCloud's proprietary network analysis....

This API returns a paginated list of the networks that a given Autonomous System (AS) is currently receiving traffic from — its upstream and peering relationships on the receiving side.It is a companion to the ASN Info Extended API, broken out as a separate paginated endpoint for cases where the full receiving-from list is large and you need to retrieve it in controlled batches. Use the ...

This API returns a paginated list of the networks that a given Autonomous System (AS) is currently transiting traffic to — its downstream routing relationships.It is a companion to the ASN Info Extended API, broken out as a separate paginated endpoint for cases where the full transit-to list is large. Use the ...

This API returns all networks currently announced on BGP within a specified CIDR range. Given a CIDR block, it returns the active sub-prefixes being routed within it, along with their ASN and registration details.It's useful for network auditing, prefix delegation analysis, and understanding how a particular IP range is being announced and routed in the current global routing table. The ...

This API returns a consolidated status report for the entire IPv4 address space, combining registry allocation data with live BGP announcement status in a single response.The data is kept current with BGP updates every two hours and registry data refreshed at least daily — making it suitable for monitoring tools that need to track allocation changes, detect unannounced or hijacked prefixes, or maintain an up-to-date view of the routable IPv4 space. For an interactive view of the same data, see the ...

This API returns a paginated list of IPv4 or IPv6 prefixes currently announced on BGP — the routing protocol that governs how traffic moves between autonomous systems on the internet.You can filter to bogon-only prefixes (unallocated or reserved address space that should not appear in global routing tables) or retrieve the full active prefix list. It's useful for route monitoring, bogon detection, and building tools that need a live view of the global routing table....

Tor routes traffic through a network of volunteer-operated nodes, with the final node — the exit node — being the IP address that destination servers see. This API returns a current list of active Tor exit nodes, geolocated to country level, along with the carrier information for each....

This API returns a ranked list of Autonomous Systems, sortable by rank, ASN number, organisation name, or country code. ASNs are ranked by the total number of IPv4 addresses they announce on BGP — a useful proxy for the relative size and reach of a network....
