Estimated users is a published estimate of how many people use this network, extrapolated from 63,938 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
- Hosts exit infrastructure for 5 different VPN brands, among them Mullvad, AirVPN and Windscribe. That is characteristic of a provider that rents capacity to several VPN operators.
- Its space resolves to 15 countries, concentrated almost entirely in United States (89% of the IPv4 space), so it is effectively a single-market network despite the spread.
- An estimated 93,527 people using this network are in United States, <0.1% of everyone online there.
Countries in this space
Space we can place in a country covers 100% of this network's IPv4 space and 100% of its IPv6 space. The table below divides that space.

Organisations holding assignments here
Registered organisations account for 0.8% of this network's IPv4 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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
| Organisation | IPv4 share | |
|---|---|---|
| Josip Sabolek | 25% | |
| MB "Ricarta" | 25% | |
| DIAMOND IP BROKERS FZCO | 25% | |
| Internet Utilities Europe and Asia Limited | 25% |
Anonymizer signals
Flagged space covers 98% of this network's IPv4 space and 100% of its IPv6 space. The table below divides that space.
| Category | IPv4 share | IPv6 share | |
|---|---|---|---|
| Datacenter | 100% | 100% | |
| Open proxy | 92% | 11% | |
| VPN | 4% | <0.1% |
One address can carry more than one of these, so the rows add up to more than the space they cover.
VPN operators using this network
Space published by a named VPN provider covers 0.3% of this network's IPv4 space and <0.1% of its IPv6 space. The table below divides that space. That counts only what providers publish as their own exits. Space merely associated with VPN use is wider, and is counted under Anonymizer signals above.
| Provider | IPv4 share | IPv6 share | |
|---|---|---|---|
| Mullvad | 34% | 81% | |
| AirVPN | 32% | 19% | |
| Windscribe | 27% | - | |
| IVPN | 5% | - | |
| ProtonVPN | 0.5% | - |
