Bandwidth and Transit Providers in China

Frequently asked questions

Who are the main transit providers in China?

viabandwidth tracks 50 IP transit and bandwidth carriers registered in China, ranging from backbone operators with the largest IPv4 holdings to regional and access carriers. The top providers by network size appear first in the directory.

What is IP transit?

IP transit is a service where a network operator carries your traffic across its own network and connects it to the rest of the internet. You pay a transit provider for bandwidth capacity, and they route your packets upstream. Transit is distinct from peering, where two networks exchange traffic directly at no cost.

What is the difference between backbone and regional carriers in China?

The network reach band reflects IPv4 holdings and internet exchange presence. Backbone carriers have the largest IPv4 allocations and broadest exchange presence. Regional carriers serve specific markets with meaningful but smaller footprints. Access carriers are last-mile or local operators. The band is derived from publicly available RIR and PeeringDB data.

How do I evaluate a transit provider?

Key factors are: IPv4 block size (a proxy for routing table depth), internet exchange presence (where peering happens), latency to your target markets, and SLA terms. The operator dossier unlocked via credits gives you verified contact routes and network intelligence for each provider.
