United States · hosting / infrastructure · registered in United Kingdom
Estimated users is a published estimate of how many people use this network, extrapolated from 2,087 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.
- Its space resolves to 10 countries, concentrated almost entirely in United States (92% of the IPv4 space), so it is effectively a single-market network despite the spread.
- The same operator runs 1 other network, and a larger one (AS201106) carries more of their users, so this network is only part of their footprint.

Organisations holding assignments here
Registered organisations account for 32% of this network's IPv4 space and 99% of its IPv6 space. The table below divides that space. Registered holders come from the bulk whois that RIPE, APNIC and AFRINIC publish. ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.

|---|---|---|---|
| Spartan Host Ltd | 50% | 99% | |
| Ace Data Centers II, LLC | 46% | - | |
