Czechia · consumer access network
Estimated users is a published estimate of how many people use this network, extrapolated from 28,690 observations over a 60 day window. Large operators often run several networks, so a low figure can mean their customers reach the internet through a sibling network.

- An estimated 38,024 people using this network are in Czechia, 0.4% of everyone online there.
- The same operator runs 16 other networks, and a larger one (AS47232) carries more of their users, so this network is only part of their footprint.
