GuangZhou · China
PeeringDB records three internet exchanges in Guangzhou, 22 participants in total. TOHU IX is the best connected with 19, ahead of CN-IX-GZ with 2 and CHN-IX Guangzhou with 1. Three colocation facilities are listed, holding three networks between them. A Guangzhou IP address tells you which operator registered the block, not where the device is.
Internet exchanges in GuangZhou
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 |
|---|---|---|
TOHU IX | 19 | none in the registry |
CN-IX-GZ | 2 | none in the registry |
CHN-IX Guangzhou CHN-IX China Guangzhou | 1 | none in the registry |

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 |
|---|---|---|
| China International Electronic Commerce Center | 3 | 3F, Building C2, Information Port, Keyun Road, Tianhe District, Guangzhou |
| BigOne Innovation Park | 0 | 6th Floor, G6 Building, South China Advanced Materials Innovation Park |
| BDx CAN1 - Guangzhou | 0 | Huangpu District |
What a GuangZhou IP address tells you
Guangzhou's recorded peering is concentrated in one exchange. TOHU IX carries 19 of the 22 exchange participants PeeringDB lists in the city, while CN-IX-GZ has 2 and CHN-IX Guangzhou has 1. The three colocation facilities add little on top of that. China International Electronic Commerce Center accounts for all three networks recorded in facilities, and BigOne Innovation Park and BDx CAN1 - Guangzhou have none. None of the three exchanges lists a mobile ASN belonging to China Mobile, China Telecom or China Unicom among its participants.
An address that geolocates to Guangzhou can be announced from wherever the origin operator chooses. China Mobile holds eight mobile ASNs in the carrier registry, and China Telecom and China Unicom hold one each, so a block registered under any of them can carry traffic that enters and leaves the network through gateways in other cities. Geolocation databases copy the address an operator publishes in its registry record, which puts a whole range on Guangzhou even when the devices using it sit far from the city.
Read the origin ASN on the specific prefix rather than the city label. An announcement from one of China Mobile's eight ASNs, from AS4134 at China Telecom or from AS4837 at China Unicom tells you which network holds the address, and the netname and registered address on that prefix tell you what the operator itself claims about it. The Guangzhou exchange records, 22 participants and no carrier ASNs among them, say nothing about where any individual handset is.
Mobile carriers in China
A mobile address in GuangZhou 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 exchanges are in Guangzhou?
PeeringDB lists three. TOHU IX has 19 participants, CN-IX-GZ has 2 and CHN-IX Guangzhou has 1, so 22 in total. The registry also holds three colocation facilities in the city, and only China International Electronic Commerce Center has networks recorded in it, three of them.
Do China mobile carriers peer in Guangzhou?
Not in these records. None of TOHU IX, CN-IX-GZ or CHN-IX Guangzhou lists a mobile ASN from China Mobile, China Telecom or China Unicom among its participants. The operators may still exchange traffic in the city outside the exchanges, and PeeringDB would not show that.
Does an IP that geolocates to Guangzhou mean the device is there?
No. The address tells you which operator announces the prefix, and geolocation databases follow the location that operator publishes for the block. Mobile traffic leaves through a small number of gateways, so a device elsewhere in China can present a Guangzhou address.
