China Telecom CN1 Network Analysis | Generated by AI
Based on the traceroute you shared from a Meiyijia convenience store WiFi in Guangzhou, this appears to be using China Telecom’s standard ChinaNet backbone (often referred to as CN1), not the premium CN2 network. Here’s a quick breakdown of why:
Key Indicators from the Traceroute
- Hops 5–10 (China Telecom backbone): IPs like 14.147.135.198, 183.56.34.41, 202.97.93.89–202.97.116.210, and 203.215.237.42 are all part of AS4134 (ChinaNet), China Telecom’s main domestic/international backbone. These are common on standard broadband lines.
- 202.97.x.x range is specifically ChinaNet (not CN2).
- 203.215.237.42 is located in Xiamen, Fujian (still within China), owned by CHINANET Fujian Province Network (AS4134).
- No CN2 signatures: CN2 (AS4809) typically shows IPs in ranges like 59.43.0.0/16 or 121.59.0.0/16 during the backbone phase. Your trace doesn’t hit any of those.
- Exit path: Traffic exits China via a standard ChinaNet handoff to Microsoft (Azure) in Tokyo (hop 11: 104.44.235.92), then routes south to Singapore (hops 14–15). This is a common, non-optimized path for basic China Telecom connections—detouring through Japan adds ~300ms latency, which aligns with CN1 congestion. CN2 often uses direct Hong Kong or shorter Asia-Pacific exits for lower latency (~150–200ms to GitHub from Guangzhou).
- Context: Meiyijia stores in Guangzhou usually run on China Telecom’s consumer/commercial broadband, which defaults to ChinaNet (CN1) unless explicitly upgraded to CN2 GIA (a paid enterprise add-on).
CN1 vs. CN2 Quick Comparison
| Aspect | CN1 (ChinaNet) | CN2 (Premium) |
|---|---|---|
| AS Number | AS4134 | AS4809 |
| Typical Latency to GitHub (from Guangzhou) | 250–400ms (congested, indirect routes) | 100–200ms (optimized, direct exits) |
| IP Ranges | 202.97.x.x, 183.56.x.x, etc. | 59.43.x.x, 121.59.x.x, etc. |
| Use Case | Standard home/business broadband | VPS/cloud/enterprise (extra cost) |
| Path Style | Often detours (e.g., via Japan/Korea) | Direct to HK/US/Asia hubs |
If you want to confirm or test further:
- Run
traceroute github.comduring peak hours (e.g., evenings) to check for more congestion. - Ping a CN2 test site like
www.cn2.net—if latency is under 200ms, you might have partial CN2 access. - Contact Meiyijia or China Telecom support for your line type (mention “CN2 GIA” if upgrading).
