Estimated users is a published estimate of how many people use this network, extrapolated from 366 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

• Carries VPN exit infrastructure for ProtonVPN.
• 33% of the flagged IPv4 space here is VPN-related, which is high enough that traffic from this network should not be assumed to be end users.
• Of those, 1,446 are in Switzerland, <0.1% of everyone online there.
• The same operator runs 3 other networks, and a larger one (AS208172) carries more of their users, so this network is only part of their footprint.
