Five questions you definitely want to ask

Q: Can't I use the free agent?
A: Free proxy is like toilet paper in a public toilet, looking at the use of the fact that other people use the leftovers. ipipgo's IP pool are raised by their own "domesticated IP", clean and hygienic.

Q: Will IP switching too often be recognized?
A: This thing is about a sense of rhythm. Ordinary sites cut 3-5 times per minute is not a problem, if you meet the bank level of anti-climbing system, you have to use ipipgo's intelligent switching mode.

Q: Why are residential IPs more expensive than server room IPs?
A: It's like living in a hotel, the IP of the server room is the express hotel, and the IP of the residence is the bed and breakfast. The website recognizes the authenticity of the residential IP more, and the cost is naturally higher.

Q: Can I use more than one agent for a plugin?
A: Of course you can! Create multiple license keys in the ipipgo backend and assign different channels to different plugins, so that even if a certain IP is banned it doesn't delay other tasks.

Q: What can I do if the proxy latency is too high?
A: In the control panel of ipipgo, there is a "speed map", choose the node with the closest physical distance. For example, if you are in Guangzhou, you should choose Shenzhen server room, and the delay can be reduced to less than 50ms.
