China · consumer ISP
Estimated users is a published estimate of how many people use this network, extrapolated from 14,398,354 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 121,928,905 people use this network, from 14,398,354 observations over a 60 day window, which puts it among the larger access networks in China.
- Its space resolves to 4 countries, concentrated almost entirely in China (100% of the IPv4 space), so it is effectively a single-market network despite the spread.
- Of those, 121,444,630 are in China, the largest of the 2 countries it serves, 15% 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.

| China | 100% | 100% | |
| Everything else (3 more) | <0.1% | - |
Organisations holding assignments here
Registered organisations account for <0.1% 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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.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 | |
|---|---|---|
| China Unicom | 86% | |
| Beijing CNISP Technology Co., Ltd. | 5% | |
| China Unicom Co Ltd Jilin Branch | 5% | |
| Chongqing and Technology Co., Ltd. | 3% |
Anonymizer signals
Flagged space covers <0.1% of this network's IPv4 space. The table below divides that space.
| Category | IPv4 share | |
|---|---|---|
| Open proxy | 100% | |
| Datacenter | 5% |
One address can carry more than one of these, so the rows add up to more than the space they cover.
Every figure on this page is also JSON: /api/v2/directory/asn/4837. Breakdowns paginate from there, so a table showing the largest rows here returns all of them. Read the API.
