Free Proxy IP Capture + Verification + Storage Complete Python Script Sharing

First, free proxy IP collection skills

The most direct way to get proxy IP resources is toReal-time crawling through public websites. It is recommended to use Python's requests library with regular expressions to target common proxy publishing platforms for targeted collection. For example, write the crawler logic like this:

import requests
import re

def scrape_proxies(): url = "" Replace with the real collection address.
    url = "https://example-proxy-list.com" Replace with the real collection address.
    resp = requests.get(url)
    ip_pattern = r'd+.d+.d+.d+.d+:d+'
    return re.findall(ip_pattern, resp.text)

Be careful to set a reasonable request interval (3-5 seconds is recommended) to avoid the access pressure on the target website. Some platforms will block IPs with high frequency access, at this time you can access theDynamic Residential Proxy for ipipgoto rotate request IPs, their pool of 90 million+ real residential IPs effectively circumvents anti-crawl mechanisms.

II. Core methods for validating the effectiveness of proxies

Captured proxy IPs with more than 70% are invalid and must pass double verification:

It is recommended to use multi-threading to speed up the verification process, live code example:

from concurrent.futures import ThreadPoolExecutor

def check_proxy(proxy)::
    try: resp = requests.get('')
        resp = requests.get('https://httpbin.org/ip',
                          proxies={'http': proxy}, timeout=5))
                          timeout=5)
        return proxy if resp.status_code == 200 else None
    return None
        return None

def validate_proxies(proxy_list): with ThreadPoolExecutor(20) as executor: validate_proxies(proxy_list)
    with ThreadPoolExecutor(20) as executor: results = executor.map(check_proxy, proxy_list).
        results = executor.map(check_proxy, proxy_list)
    return [p for p in results if p]

III. Intelligent Storage Solution for Proxy IP

RecommendedSQLite databasePerforms local storage and contains three core fields:

CREATE TABLE proxies(
    ip TEXT PRIMARY KEY, speed REAL, ip TEXT PRIMARY KEY, ip TEXT
    speed REAL, last_check TIMESTAMP
    last_check TIMESTAMP
)

It is recommended to set up a timed task to automatically clean up unverified IPs for 3 days at dawn every day. for enterprise level application scenarios, it is straightforward to use theAPI interface for ipipgoGet authenticated proxies in real time, and their residential IPs support the full SOCKS5/HTTP/HTTPS protocols, saving maintenance costs.

IV. Answers to frequently asked questions

Q: What should I do if my free proxy fails frequently?
A: Free IP survival time is generally 2-12 hours, commercial-grade scenarios recommend the use of ipipgo's static residential IP, a single IP can maintain a stable connection for up to 24 hours.

Q: Lots of ConnectionError when authenticating?
A: It may be caused by the mismatch of protocol types. ipipgo supports the automatic protocol adaptation function, which can intelligently identify the best way to access the target website.

V. Why choose professional agency services

When faced with the need toHigh Frequency Replacement IPmaybeMulti-region IP switchingThe cost of maintaining a self-built proxy pool rises exponentially in business scenarios. ipipgo covers real residential IP networks in more than 240 countries and regions, and is particularly well suited for organizations that need toPrecise geographic locationof business needs.

Their technical service team provides 7×24 hour node monitoring to ensure IP availability is always above 99%. With the free SDK access program, developers can complete the integration of the agent system within 10 minutes, significantly improving development efficiency.
