United Kingdom · consumer ISP
Estimated users is a published estimate of how many people use this network, extrapolated from 8,687,074 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 17,124,100 people use this network, from 8,687,074 observations over a 60 day window, which puts it among the larger access networks in United Kingdom.
- Carries VPN exit infrastructure for NordVPN.
- Its space resolves to 15 countries, concentrated almost entirely in United Kingdom (99% of the IPv4 space), so it is effectively a single-market network despite the spread.
- Of those, 17,124,100 are in United Kingdom, 26% of everyone online there.
- 95 distinct organisations hold registered assignments inside this space, so an address here often belongs to one of their customers.
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 Kingdom | 99% | 100% | |
| United States | 1% | <0.1% | |
| Everything else (13 more) | <0.1% | <0.1% |
Organisations holding assignments here
Registered organisations account for 99% of this network's IPv4 space and 100% 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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.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 | |
|---|---|---|---|
| British Telecommunications Limited | 78% | 94% | |
| EE Limited | 19% | 6% | |
| Aviation RE LLC | 0.5% | - | |

Anonymizer signals
Flagged space covers 0.2% of this network's IPv4 space and <0.1% of its IPv6 space. The table below divides that space.
| Category | IPv4 share | IPv6 share | |
|---|---|---|---|
| Open proxy | 100% | - | |
| Datacenter | 96% | - | |
| VPN | 22% | - | |
| Not covered by any of these | - | - |
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 | |
|---|---|---|
| NordVPN | 100% |
