Global network topology spanning a luminous Earth

Internet mapping for a continuously changing Internet

Observe how networks, routes, addresses, exchange points, and reachable endpoints connect—and turn that changing topology into a verified Knowledge Graph for operational risk analysis.

Map the whole system

Connect autonomous systems, routes, paths, prefixes, and dependencies in one model.

Verify what is reachable

Test active IPv4 and IPv6 endpoints from distributed Internet locations.

Act on every change

Trace new exposure, outages, anomalies, and potential blast radius as conditions change.

What is internet mapping?

A living model of the infrastructure behind every Internet service

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.

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.

How modern internet mapping works

A verified operational map connects route intelligence, active measurement, and graph analysis without treating any single signal as complete.

01

Map routes and paths

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.

02

Verify active reachability

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.

03

Analyze the connected graph

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

Different Internet mapping approaches answer different questions

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.

Compare approaches

What an operational Internet map can reveal

Internet mapping extends internal monitoring outward, exposing the external infrastructure and path dependencies that shape how services are reached.

Hidden dependencies

Identify upstream providers, shared transit, and indirect infrastructure that internal inventories often miss.

Fragile chokepoints

Measure true backbone and fragile chokepoints with graph centrality.

Routing anomalies

Investigate route changes, leaks, hijacks, and unexpected path behavior with connected context.

Reachability failures

Determine whether IPv4 or IPv6 endpoints remain responsive across different network locations.

Sovereign paths

Trace which networks, geographies, and jurisdictions an Internet path traverses.

Potential blast radius

Model how a provider failure, route disruption, or concentrated dependency could affect connected services.

Frequently asked questions

Answers for evaluating Internet intelligence

View technical FAQ
What is internet mapping?

Internet 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.

How is internet mapping different from network monitoring?

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.

Why combine BGP data with active reachability?

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.

What can teams do with an Internet Knowledge Graph?

Teams can traverse connected route, network, endpoint, and historical relationships to investigate hidden dependencies, chokepoints, routing anomalies, sovereign paths, and potential disruption impact.

Does internet mapping show the exact path of every packet?

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.
