Spain · consumer access network

Estimated users is a published estimate of how many people use this network, extrapolated from 2,442 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

• An estimated 4,542 people using this network are in Spain, <0.1% of everyone online there.
• The same operator runs 1 other network, and a larger one (AS21193) carries more of their users, so this network is only part of their footprint.
