Glossary

Due to the complexity of the network in mainland China, the following description may not be 100% accurate and is for reference only.

Communication optimization
Mobile Optimization: Network optimization for China Mobile (may not cover 100% of areas)

Unicom Optimization: Network optimization for China Unicom (may not cover 100% of areas)

Telecom Optimization: Network optimization for China Telecom (may not cover 100% of areas)

Three network optimization: network optimization for all three carriers — China Telecom, China Unicom, and China Mobile (may not cover 100% of areas)

International optimization: direct line, no China network optimization, suitable for international users outside mainland China.

Mainland optimization: It can ensure the network connectivity of users in mainland China at a relatively high level, especially in areas with strict network control such as Quanzhou and Henan in Fujian.

Optimized lines: There is certain mainland network optimization


Feature optimization
Google IP sent

Advantages: Watch YouTube without ads
Disadvantages: It is not easy to use Google play and other related Google services, including direct access to Google.com, which is prone to 404, and you need to use Google Hong Kong:https://www.google.com.hk/
Google Singapore:https://www.google.com.sg
Google Taiwan:https://www.google.com.tw


Streaming/Netflix/GPT
They use relatively good IPs and can normally access many foreign IP-restricted services, but they may have a certain timeliness and may become invalid after a long time.


Home Broadband IP
As the name suggests, it is the IP of the network broadband installed at home. It is very pure and suitable for using various local network services.


common nouns
Ping value
The general unit is milliseconds (ms), which is the round-trip transmission time of sending data. Generally, the ping value in Asia is relatively low, such as Hong Kong, Singapore, Japan, etc. The ping value is low, usually within 100ms. From South China to Hong Kong, it may be about 20ms. In theory, it is a delay. Low and fast, but during the evening peak hours, there may be congestion and packet loss. The actual experience of watching YouTube videos may not be as good as in the United States. The ping value in the United States is about 120-160ms, but the bandwidth in the United States is relatively abundant, and the performance will be better during the evening peak hours.
