How we rank
Rankings combine multiple data sources — internet-wide measurements, routing tables, and partner traffic samples — normalised to fit on a per-network scale.
Overall ranking
A weighted blend of traffic and infrastructure rankings, designed to surface networks that are important by either lens. Use this when you don't yet know which dimension matters most for your task.
Traffic ranking
Ranks networks by how many users they reach, based on unique users and traffic observed across our CDN probe network, device telemetry, and WiFi signals. The world's largest mobile carriers and consumer ISPs lead this list.
Infrastructure ranking
Measures routing criticality — combining BGP path analysis (how many internet paths transit through a network) with router presence discovered via traceroutes. Tier-1 transit providers and backbone networks dominate.
Country ranking
The combined ranking restricted to networks registered to the same country, so you can compare like-for-like in any market.
Limits and refresh cadence
Rankings are computed from 90-day rolling data and refresh monthly. Networks brand-new to the routing table or with very little observable traffic may surface as unranked. We document the underlying data sources and update our methodology as the dataset matures — get in touch if you need access to the underlying signals.

Monthly-refreshed rankings
All four rankings (traffic, infrastructure, combined, country) updated on every monthly dataset refresh.
Underlying signals
Access CDN probe, device telemetry, WiFi, BGP hegemony, and traceroute router counts — not just the final rank.
History and deltas
Track how a network's rank changes over time and spot infrastructure shifts as they happen.
