AS4134 is China Telecom's primary backbone ASN — the largest ISP in China and one of the largest in the world by subscriber count. China Telecom operates the ChinaNet backbone, which is one of three state-owned networks (alongside China Unicom AS4837 and China Mobile AS9808) that collectively carry all Chinese internet traffic. International connectivity passes through tightly controlled gateways that enforce the Great Firewall of China.
Every time you visit a website, your IP address — and therefore your ISP (China Telecom) — is visible to that site. China Telecom as your ISP can see all unencrypted traffic passing through their network, including the domains you visit. This is standard practice for all ISPs and is typically used for network management, legal compliance, and in some cases targeted advertising.
If your device is assigned an IP in China Telecom’s ranges, websites you visit will identify your connection as coming from China Telecom. To prevent this, a VPN replaces your ISP-assigned IP with the VPN server’s IP, making your traffic appear to come from a different provider entirely.
AS4134 is registered with APNIC — the Regional Internet Registry responsible for IP allocations in the Asia Pacific region. The ASN is used to announce IP prefixes to the global BGP routing table, allowing other networks to route traffic to China Telecom’s infrastructure.
China Telecom peers with major transit providers and internet exchanges to ensure global reachability. BGP peering relationships determine how traffic flows between China Telecom and the rest of the internet.
