Germany · hosting / infrastructure
Estimated users is a published estimate of how many people use this network, extrapolated from 25 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.
What this tells you
- Classified as hosting infrastructure. The handful of users measured behind it are people browsing from servers, not subscribers.
- The population figure rests on 25 observations, so read it as an order of magnitude.
- The same operator runs 2 other networks, and a larger one (AS201011) carries more of their users, so this network is only part of their footprint.
