IP Rotation Proxy Server: Automatic Switching Anti-Blocking Solution

Playing up the IP rotation is the right way to prevent blocking.

Friends who engage in network collection understand that IP blocked is as common as eating and drinking water. Yesterday, just built a good crawler, this morning, a break. At this time we have to offer our killer -The Great IP RotationThis is the first time I've seen this. Don't look down on this trick, use the right one can make you double the collection efficiency, use the wrong one as usual to be sealed to cry father and mother.

IP rotations are not random. Here are three tips to remember.

Many people think that IP rotation is a timed switch, but in fact, there are a lot of doors here. Based on our experience serving 300+ organizations, it has to be based on these three dimensions:

Take ipipgo's customer case for example, there is an e-commerce price comparison team, the original was blocked more than 50 IP every day.Dynamic Rate + Hybrid IP PoolAfter that, it now runs for a week straight without a break. They use ipipgo's smart rotation program, I'll get into exactly how that works later.

Hands-on Rotation System

Here's a real-world Python example, using the requests library + ipipgo's API to automate switching. Pay attention to the comments section, it's all blood and tears experience:

import requests
import random
from time import sleep

def get_new_ip():: This calls the ipipgo API to get a new IP.
     Here we call the ipipgo API to get a new IP.
    api_url = "https://api.ipipgo.com/get?type=rotate"
    resp = requests.get(api_url).json()
    return f"{resp['ip']}:{resp['port']}"

current_proxy = get_new_ip()
request_count = 0

while True: current_proxy = get_new_ip()
    request_count = 0 while True: current_proxy = get_new_ip()
        proxies = {"http": current_proxy, "https": current_proxy}
         Remember to set a timeout so you don't have to wait forever
        resp = requests.get('Target site', proxies=proxies, timeout=10)
        print("Successful capture!")
        request_count +=1

         Here comes the key! Dynamic switching strategy
        if request_count > random.randint(50,80): random switching threshold
            current_proxy = get_new_ip()
            request_count = 0
            sleep(random.uniform(0.5,3)) add a random delay

    except Exception as e.
        current_proxy = get_new_ip(", e)
        current_proxy = get_new_ip() change IP immediately
        request_count = 0

The essence of this script is in theRandom switching thresholdrespond in singingAbnormal second changeMechanism. Much more reliable than those fixed time switching programs, pro-measurement can reduce the probability of IP blocking 70% or more.

the right IP pool doubles the effect and halves the effort

IP quality directly affects the rotation effect. I've tested a lot of proxy services on the market, and finally locked ipipgo mainly because of three points:

1. High percentage of real-life residential IP: Their dynamic residential IP pool is much harder to recognize than pure server room IPs
2. Toggle senseless: The API response is fast enough that the business doesn't lag when changing IPs.
3. Wide geographical coverageIPs can be cut in seconds for any city you want, especially for businesses that require geographic targeting.

Last week to help customers do stress testing, with ipipgo's rotation scheme continuously sent 200,000 requests, the survival rate can still be maintained at 98% or more. This data in the industry is considered quite beatable.

Frequently Asked Questions QA

Q: Is it expensive to change IPs frequently?
A: ipipgo's billing model is quite flexible, how much you use. And they send 5G of traffic for new users, which is enough for testing.

Q: How can I tell if an IP is a real residence?
A: Teach you a dirt method to use IP to check the weather site. If the returned weather and IP location does not match, 80% is the IP of the server room. ipipgo's IP I have checked the accuracy rate of 90% or more!

Q: What if I want more than one IP at the same time?
A: They have concurrent channel function, just open more than one API connection. Remember to use different authentication parameters for each channel so that the IP segments are different.

Tell the truth.

IP rotation is like playing whack-a-mole. The rules of IP blocking change every day, and our coping strategies have to be upgraded as well. Recently, I found that some websites have started to detectIP switching patternThe ones that switch at fixed intervals are especially easy to catch.

Suggest the guys try ipipgo'sIntelligent switching algorithmIt can automatically adjust the strategy according to the anti-climbing strength of the target website. Use down the most intuitive feeling is to save heart, do not have to stare at the log all day to see if there is blocked.

One last word of caution, don't waste your time on free proxies. I've stepped in a pit before, and 8 out of 10 free IPs were black, and they were blocked before I even started using them. Professional things are still left to the professionals to do, save time to engage in more business does not smell good?
