AS3598: Microsoft Corporation

United States

Estimated users is a published estimate of how many people use this network, extrapolated from 4,438 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

• Its space resolves to 10 countries, concentrated almost entirely in United States (96% of the IPv4 space), so it is effectively a single-market network despite the spread.
• The same operator runs 62 other networks, and a larger one (AS8075) carries more of their users, so this network is only part of their footprint.
