Rotation of ISP agents: automatic switching of anti-blocking systems

What the heck is a rotating ISP agent?

To put it bluntly, it allows IP addresses of different carriers to switch automatically. For example, you are now using the telecom line, later automatically cut to Unicom, and then cut to mobile. This trick against some sites blocking IP is particularly effective, like a guerrilla war, so that the blocking system can not feel the law.

Take a real scenario: Zhang San does e-commerce data collection, every time you access it with a fixed IP, it will be blocked in less than half an hour. Later, he changed toAutomatically change IP of different carriers every 15 minutes, ran fine for three days straight. That's the core value of rotating ISP agents - theFighting Banning with ChangeThe

Hands-on guide to building an automatic switching system

Don't be intimidated by the jargon, there are really just three steps at the core:

 Sample code (Python version)
import requests
from random import choice

def get_ipipgo_proxy():
     Get the latest proxy pool from ipipgo
    api_url = "https://api.ipipgo.com/isp-pool"
    proxies = requests.get(api_url).json()
    return choice(proxies) Randomly choose a carrier IP

 This is what you use for the actual request
current_proxy = get_ipipgo_proxy()
response = requests.get("target site", proxies={
    "http": f "http://{current_proxy}",
    "https": f "http://{current_proxy}"
})

Pay attention to these few practical details:

- Don't be rigid about the timing of the switch.: Don't fix 10 minutes to change once, you can set 5-15 minutes random intervals
- Operators want to disruptDon't do Telecom→Unicom→Telecom, you should switch randomly.
- Failure to retry automatically: Switch to the next IP immediately when the connection fails, don't wait!

What makes ipipgo suitable for this scenario?

There are many agency service providers on the market, but to do sostable rotationThree conditions must be met:

White Frequently Asked Questions QA

Q: What is the difference between a rotating agent and a regular agent?
A: Ordinary agents are like fixed workstations, and rotating agents are like mobile stalls, which are more suitable for scenarios that require long-term stable operation

Q: Do I need to write my own code to use ipipgo?
A: They provide ready-made rotation tools, but it's more flexible to use the API if you know how to program (there is detailed documentation on the official website)

Q: Will switching too often be recognized instead?
A: The key toSimulation of real-life operationIt is recommended that the frequency be adjusted according to the business scenario. For example, web page collection can be changed in 10 minutes, and ticket-grabbing operations are recommended to be 3-5 minutes.

Q: Will the blocked IP be re-assigned?
A: ipipgo's mechanism is to automatically quarantine blocked IPs, and will not repeat the allocation within 72 hours, which is a very considerate design

Don't step on these potholes.

Recently encountered a typical case: Li Si in order to save costs, set the switching interval to 1 minute, but the result instead triggered the site's wind control mechanism. It is recommended that newbies first useSmart Mode for ipipgoTheir system automatically learns the characteristics of the target site and dynamically adjusts the switching strategy.

There is also a common misconception - that all websites need to be rotated. In fact, like government websites may record IP but not blocked, this time with a fixed IP instead of more stable. Specifically, you can first use ipipgo'stest patternRun it for 24 hours and see how the target site reacts before deciding on a strategy.

Lastly, don't mix proxies from different service providers in the same task, as this can easily lead to confusion in authentication information. Stick to the ipipgo family bucket, their tech stack is optimized for rotation scenarios, which is really not comparable to others.
