The Internet is ~80,000 networks (ASes) stitched together by provider–customer and peering relationships — far too many to draw at once. These two views show its shape instead: where connectivity crosses borders, and which networks form the transit core. Both are built from CAIDA’s inferred AS-relationship graph.
Country-to-country arcs weighted by the number of AS relationships that cross between them.
Scroll to zoom · drag to pan. Arc thickness = number of AS-level relationships crossing between the two countries (CAIDA). Endpoint size = a country’s total cross-border links.
The top 300 ASes by customer cone and the inferred relationships among them — the carriers and content networks the rest of the Internet hangs off.
300 top ASes · 6,000 links. Node size ≈ customer cone, colour = transit role. Scroll to zoom · drag nodes · click an AS to open it.
Relationships are inferred from BGP by CAIDA and refreshed monthly; private and IXP peering is under-observed, so these are a conservative lower bound. Explore an individual network from the rankings or by opening any AS.
