What is internet mapping?
Internet mapping observes how networks, routes, addresses, exchange points, and reachable endpoints connect across the global Internet—and how those connections change.
It looks beyond a company's own network to the autonomous systems, transit providers, address space, and routing relationships that move traffic across the public Internet. A static diagram cannot represent that system for long: BGP routes shift, providers announce and withdraw prefixes, endpoints become unavailable, and paths move across networks or jurisdictions.
That is the difference from network mapping, which usually documents the devices, IP addresses, and links inside one organization's network. Internet mapping covers the space between networks: the peering and transit relationships among autonomous systems, the Internet exchange points where networks interconnect, and the routes that join them. The result is an Internet connectivity map that changes as routes change.
Public measurement systems show why useful mapping needs more than one source. The RIPE NCC Routing Information Service collects BGP data to make routing behavior observable, while RIPE Atlas uses distributed probes to measure connectivity and reachability. CAIDA's Internet topology work combines active path probing with BGP-derived mappings to construct IPv4 and IPv6 connectivity graphs.
The goal is not simply to draw the Internet. It is to answer questions about dependency, exposure, performance, resilience, and compliance with evidence that can be examined over time.
A verified operational map connects route intelligence, active measurement, and graph analysis without treating any single signal as complete.
Observe BGP announcements, withdrawals, prefixes, and path vectors to understand which autonomous systems participate in a route and how routing conditions are changing.
Routing observations are essential evidence, but they do not by themselves prove that an endpoint is responding or that packets follow an assumed path.
Test whether IPv4 and IPv6 endpoints actually respond from distributed Internet locations, then compare those results with route and path changes.
This separates control-plane change from verified availability impact and helps localize failures by region, network, or provider.
Link routes, paths, endpoints, and historical changes in a Knowledge Graph so teams can traverse relationships instead of reviewing disconnected feeds.
Graph analysis reveals concentrated dependencies, shared transit, critical chokepoints, and the possible blast radius of disruption.
Choose the right evidence
BGP visibility, active probing, static diagrams, and a connected Knowledge Graph differ in what they can observe, verify, and support. Compare the evidence before deciding what your team should rely on.
Internet mapping extends internal monitoring outward, exposing the external infrastructure and path dependencies that shape how services are reached.

Explore solutionInternet mapping is the continuous observation and organization of Internet networks, BGP routes, path relationships, address space, exchange points, and endpoint reachability. It turns distributed technical observations into a model teams can use to understand dependencies and change.
Network monitoring usually focuses on infrastructure an organization owns or directly manages. Internet mapping extends the view across external autonomous systems, transit providers, routes, and globally distributed endpoints that influence how services are reached.
It shows how autonomous systems interconnect, including relationships formed at Internet exchange points, as reflected in observed BGP AS paths. That helps teams see which networks sit between them and the services they depend on. Internet Mapper observes routes from 500 crawlers, including all major Internet exchanges, and links those relationships with active reachability in its Knowledge Graph.
BGP data shows how networks announce and exchange route information. Active reachability shows whether IPv4 and IPv6 endpoints actually respond from different locations. Combining both helps distinguish a routing event from a verified availability impact.
Teams can traverse connected route, network, endpoint, and historical relationships to investigate hidden dependencies, chokepoints, routing anomalies, sovereign paths, and potential disruption impact.
No. BGP observations are control-plane evidence about advertised routes and AS paths. Active probes add observed reachability from a defined test context, but neither signal alone proves the exact forwarding path of every packet.
