What this tells you
- Carries VPN exit infrastructure for Surfshark.
- Its space resolves to 4 countries, concentrated almost entirely in United States (99% of the IPv4 space), so it is effectively a single-market network despite the spread.
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.
| Country | IPv4 share | IPv6 share | |
|---|---|---|---|
| United States | 99% | 100% | |
| Singapore | 0.6% | - | |
| Canada | 0.3% | <0.1% | |
| Türkiye | 0.3% | - |
Organisations holding assignments here
Registered organisations account for 43% of this network's IPv4 space and 2% 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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
| Organisation | IPv4 share | IPv6 share | |
|---|---|---|---|
| Internet Utilities Europe and Asia Limited | 21% | - | |
| C4K5 LLC | 11% | - | |

Anonymizer signals
Flagged space covers 100% of this network's IPv4 space and 100% of its IPv6 space. The table below divides that space.
| Category | IPv4 share | IPv6 share | |
|---|---|---|---|
| Open proxy | 100% | 100% | |
| Datacenter | 47% | 49% | |
| VPN | 21% | - |
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 <0.1% of this network's IPv4 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 | |
|---|---|---|
| Surfshark | 100% |
