ISP Dynamic IP: Broadband dial-up IP automatic replacement script development tutorials

What's so great about dynamic broadband dial-up IP?

To put it bluntly, ordinary fixed IP is like renting a house must sign a three-year contract, and dynamic IP is to rent a hostel bed as you go. Those who are engaged in data collection know thatIt is common for IPs to be blackballed by target sitesThis is the time when changing IPs automatically is as important as changing your clothes. ipipgo's pool of dynamic residential IPs is bottomless, with more than 90 million real home network addresses around the globe, more flexible than a chameleon.

Pre-Development Preparation

First of all, you need to have a handy toolkit: Python environment (recommended version 3.6 or above), requests library, ipipgo's API docking documentation. Let's focus on ipipgo'sFull Protocol SupportThe interface returns data with a full set of authentication parameters, regardless of whether it is HTTP or SOCKS5, so you don't have to fiddle with the protocol conversion yourself.

Hands-On Auto Replacement Scripts

As a chestnut, getting an IP with ipipgo's API is like buying a drink from a vending machine:

import requests
import time

def get_ip(): response = requests.get("")
    response = requests.get("https://api.ipipgo.com/dynamic", params={"type": "http"}))
                          params={"type": "http"})
    return response.json()['ip'] + ":" + str(response.json()['port'])

while True: current_ip = get_ip('port')
    current_ip = get_ip()
    proxies = {"http": f "http://{current_ip}",
               "https": f "http://{current_ip}"}
    https": f"{current_ip}"}
        resp = requests.get("target site", proxies=proxies, timeout=10)
        print("Current IP is working:", current_ip)
    except.
        print("! Triggering replacement mechanism!")
        current_ip = get_ip()
    current_ip = get_ip() time.sleep(600) 10 minutes to change the IP

Watch this.Exception Handling ModuleIt is the core, when encountering access failure immediately triggers IP replacement. ipipgo's interface response speed is controlled within 200ms, IP replacement is more than 20 times faster than manual dialing.

A few potholes that are easy to fall into

1. Don't blindly set the IP survival time: the dynamic IP validity period varies greatly from region to region, it is recommended to test the average survival time of IPs around the world. ipipgo's IPs are available for an average of 15-30 minutes.

2. Authentication information to bring the full: many newbies will miss the password field, their API return data are contained in theusername/passwordfield, remember to fill in the proxy parameters

3. Switching frequency is not too high: although ipipgo's IP pool is large enough, it is recommended that a single account request no more than 3 times per second.

Frequently Asked Questions QA

Q：IP shows successful but can't access the website?
A: First check whether the proxy format is correct, ipipgo port 80/443/8080 three kinds of different business scenarios to choose the corresponding port

Q: What happened to the script running suddenly slow?
A: 80% is not set local DNS, in the code to add a barrequests.packages.urllib3.disable_warnings()try out

Q: What if I need to manage multiple IPs at the same time?
A: ipipgo supports multi-channel concurrent acquisition, in the API parameter add a?count=5You can get 5 different IPs at once.

As a final rant, dynamic IP management is like raising fish, where you have to change the water (IP) regularly and pay attention to how much you feed (request frequency). With ipipgo's Residential IP Resource Pool, it is equivalent to contracting an entire oceanarium, and you can swim however you want. Their technical support team is online 24 hours a day, and you can directly dump code over for help when you encounter scripting problems.
