China Unicom
Address space registered to China Unicom, and where it is announced from.
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 ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
What this tells you
- Holds 16,384 IPv4 addresses across 1 registered block.
- Announced entirely by AS4837 China Unicom Backbone.
- All of the space we can place resolves to China.

Holding a block is a registry fact, not a physical one. The organisation named here is who the block is assigned to, which is often a customer of the network operator announcing it.
