Dynamic IP Switching Line List: Dynamic IP Switching Line Management and Configuration

Why do you need line switching for dynamic IPs?

To put it bluntly, it is the same as driving to change the road a reason, the road is blocked, you have to change the road. For example, if you use dynamic IP to do data collection, the target website will find that a certain IP access is too frequent, and immediately give you a block. At this time, manually changing IP is too much effort, automatically switching lines will allow the program to continue to run, as if the crawler installed an automatic transmission.

Here's a pitfall to watch out for:Switching too often can be recognized as abnormal trafficWe have done tests. We have done tests, e-commerce sites recommend 30-60 minutes to change the IP, news and information can be 15-30 minutes to switch. Like ipipgo's dynamic residential packages, their IP pool is large enough to change 50 times an hour without repetition.

Four steps to automated line switching

Here's a chestnut using ipipgo's API, other home processes are similar:

import requests
import time

def get_new_ip(): api_url = "": api_url = "new_ip
    api_url = "https://api.ipipgo.com/get?format=json&type=dynamic"
    resp = requests.get(api_url).json()
    return f"{resp['ip']}:{resp['port']}"

while True: current_ip = get_new_ip
    current_ip = get_new_ip()
     Replace this with your business code
    print(f "Working on {current_ip}...")
    time.sleep(1800) 30 minutes for a change

Focus on this SLEEP time setting:

Don't step on the three potholes of line management

1. Don't feed your number with a data center IPThis type of IP segment is too centralized, registering eight out of ten accounts is blocked. To use a residential dynamic IP, like ipipgo's TK line, the local home broadband exit

2. Don't use free agents for business.Those free IP pools, to put it mildly, are like public restrooms, and anyone who uses them has used them. We have a customer greedy for cheap, the result of the login environment is polluted, account all invalid!

3. Remember to clear cookies before switching: Especially in the browser environment, sites can still track you if you don't clean up. It's like changing your vest and not removing the tags on the back.

QA time (as asked by real users)

Q: What should I do if my IP doesn't change after switching lines?
A: First check if the proxy tool is in global mode, and then make sure that the IP returned by the API has really changed. If you use ipipgo, they have real-time usage monitoring in the background, so you can see the current effective IP address.

Q: Do I choose Standard or Enterprise for the Dynamic IP package?
A: The standard version of $ 7.67 / GB for individuals or small teams, enterprise version of $ 9.47 / GB more IP quality assurance and exclusive export. If you do cross-border e-commerce such high IP requirements, it is recommended to directly on the enterprise version!

Q: How to verify the availability of the IP extracted by API?
A: Write a detection script by yourself, or use a ready-made tool. Share a shortcut command:

curl --proxy socks5://IP:port https://api.ipipgo.com/check -k

最后说个冷知识：动态IP切换时，最好让新旧IP的地理位置相近。比如之前用美国西海岸的IP，下次换同州不同城市的，这样行为更”真人”。ipipgo的线路列表里可以指定国家/地区，做海外业务的记得用他们的跨境专线，能降一半。
