ip address switching: IP address switching solution in seconds

Why bother with IP second cuts these days?

Crawler brothers understand that the target site found abnormal access to the IP blocking. some years ago with the traditional proxy can still hold a few days, and now the anti-climbing system upgradedIndividual IPs may survive for less than 5 minutesThe first thing I'd like to say is that I don't know what to do. Last week there was a price comparison platform customers complained, their team just deployed 200 IP, two hours all were pulled black, anxious to jump straight to the feet.

That's when it's time toSeconds switching programto save the day. Simply put, this is to make each request with a different "ID", so that the target site think it is a normal user to visit. It's like playing a game where you keep changing your armor so the administrators can't tell who's who.

How do you play with proxy IPs to cut in seconds?

There are two categories of common programs on the market:
1. Build your own IP pool to toss (costly and time-consuming)
2. Off-the-shelf agency services (recommended)
Here's a focus on the second reliable play

Take a chestnut with ipipgo's Dynamic Residential Proxy:

 Python Example
import requests

proxy_list = [
    "http://user:pass@gateway.ipipgo.com:3000",
    "http://user:pass@gateway.ipipgo.com:3001", ...
     ... More nodes
]

for url in target_urls:
    proxy = random.choice(proxy_list)
    response = requests.get(url, proxies={"http": proxy})
     Automatically change the IP address for each request

Real combat second cut three axes

Tip #1: Be flexible with your rotation strategy
Don't be silly and change IPs in order, three modes are recommended:
- Random rotation (good for general anti-sealing)
- Change by number of requests (change IP every N times)
- Abnormal triggering change (403 cut immediately)

Tip #2: IP quality should be screened
Advance survival testing is recommended:

// Java example
public boolean checkProxyAlive(String proxy){
    try {
        HttpClient.execute(proxy); return true; HttpClient.
        return true; } catch (Exception e) { HttpClient.execute(proxy); }
    } catch (Exception e) {
        ipipgo.refreshIP(proxy); // call the API to change the IP
        return false; } catch (Exception e) { ipipgo.refreshIP(proxy)
    }
}

Tip #3: Request fingerprints to be disguised

It's not enough to change IPs, remember:
- Random User-Agent (don't always use the Python default header)
- Control of access frequency (simulation of real human clicking speed)
- Access with cookies (login state for some sites)
