Shenzhen · China
PeeringDB records one exchange in Shenzhen, CNIX (Qianhai, Shenzhen), with 10 participants, and two colocation facilities holding 19 network presences, GDS Shenzhen San with 10 and Shenzhen Baiwangxinyun Datacenter with 9. An address that geolocates to Shenzhen points to an operator's registry record rather than a device in the city.
Internet exchanges in Shenzhen
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.
| Exchange | Participants | Registry carriers peering |
|---|---|---|
CNIX (Qianhai, Shenzhen) China Internet Exchange (Qianhai, Shenzhen) | 10 | none in the registry |
Exchange records: PeeringDB.
Colocation facilities
Buildings where networks put equipment. The network count is how many PeeringDB members list a presence there, which shows where capacity in the city sits.
| Facility | Networks present | Address |
|---|---|---|
| GDS Shenzhen San | 10 | No.5, Taohua Road, Futian Free Trade Zone |
| Shenzhen Baiwangxinyun Datacenter | 9 | #1, Area 1, Nanshan Baiwangxin Hi-tech Industrial Park, Shahe W Rd, Nanshan Qu |
What a Shenzhen IP address tells you
Shenzhen's documented network presence divides between one exchange and two buildings. CNIX (Qianhai, Shenzhen) lists 10 participants, and the two facilities hold 19 presences between them, 10 at GDS Shenzhen San and 9 at Shenzhen Baiwangxinyun Datacenter. The counts are close, so neither the exchange nor the colocation side clearly carries the city. The exchange lists no mobile ASN from China Mobile, China Telecom or China Unicom, so the registry shows no mobile carrier peering here.
A city result of Shenzhen comes from the record attached to the address block, which the announcing operator wrote. Nothing in that record measures where a connection starts. Mobile networks concentrate subscriber traffic at a few gateways, so one registered location can stand behind users across a wide area, and geolocation databases repeat the operator's published city because that is the source available to them.
The origin ASN on the prefix identifies the network responsible for the address, and the netname shows how that network describes the range. Those two fields survive resale and reassignment better than a city label does. Whether the same ASN appears among the 10 participants at CNIX (Qianhai, Shenzhen) or in either facility record is a further check on how present the network is here.
Mobile carriers in China
A mobile address in Shenzhen is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchange is in Shenzhen?
PeeringDB records one, CNIX (Qianhai, Shenzhen), with 10 participants. The city also has two colocation facilities in the registry, GDS Shenzhen San with 10 networks and Shenzhen Baiwangxinyun Datacenter with 9, giving 19 network presences inside buildings.
Do Chinese mobile carriers peer in Shenzhen?
Not according to the registry. No mobile ASN from China Mobile, China Telecom or China Unicom is listed at CNIX (Qianhai, Shenzhen). PeeringDB depends on operators recording their own presence, so this reflects what they publish rather than a full account of their traffic.
Does an IP that geolocates to Shenzhen mean the device is there?
No. The label follows the registry record for the block. Mobile addresses trace to the gateway that assigned them, which can sit far from the handset, and databases copy the operator's stated location. The origin ASN and prefix netname give a clearer answer.
