Proxy Grabber: IP Resource Validation Scripts

Hands-On IP Validity Screening

Engaged in data collection friends understand, find a proxy IP can be used like a needle in a haystack. Those free agents on the Internet look quite a lot, in fact, nine out of ten can not connect. At this time you have to write your own validation script, put the good steel on the knife edge. Let's take python as an example, with the requests library you can get a basic version of the detection tool.

import requests
from concurrent.futures import ThreadPoolExecutor

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

raw_proxies = ["183.234.123.12:8888", "45.77.89.3:3128"...]   Here are the IPs to be tested
with ThreadPoolExecutor(20) as executor: alive_proxies = list(20) as executor.
    alive_proxies = list(filter(None, executor.map(check_proxy, raw_proxies)))

There are just three things at the core of this script:Be responsive(Set a timeout of 5 seconds),Enough anonymity.(detects if the returned IP is real),The location has to be right.(Filtered according to business needs). It is recommended to run a test every hour, after all, free agents say hang.

The Three Pitfalls of Building Your Own IP Pool

Those of you who maintain your own proxy pools have certainly encountered this crap:

Especially the third point, a lot of geographically restricted business in this fall. At this time it is recommended to useProxy services for ipipgoTheir base station data is ridiculously accurate, the last time I measured 50 IPs, the geolocation match rate was 98% or more.

How to choose an enterprise solution

Individuals play a free agent is okay, really want to engage in serious projects still have to find professional service providers. Here are a few hard indicators:

• ✅ Survival rate of at least 95% or more
• ✅ Median response time <2 seconds
• ✅ Support for on-demand switching of egress IPs

One of ipipgo's specialties is that theIntelligent Routing SystemThe company can automatically select the optimal line according to the target website. The last time I did cross-border e-commerce friends use his service, the collection efficiency is directly doubled.

Practical QA collection

Q: What is the difference between a free agent and a fee?
A: The main difference is in the survival time and connection quality. Free agents live less than three minutes on average, and paid ones like ipipgo can be used stably for several hours.

Q：Why does the tested IP not work when I use it?
A: There are two possibilities: 1. the target site has additional verification 2. the IP is temporarily blocked. It is recommended to add a simulated visit to the target site detection link in the script

Q: How can I prevent my IP from being banned?
A: three combinations of punches: 1. control the frequency of requests 2. randomly switch UserAgent 3. with ipipgo's dynamic port function, which is personally effective

The Ultimate Program for Saving Heart and Soul

Maintaining your own proxy pool is too much work, especially if you need massive IPs. Directly on theAPI services for ipipgoThe company's concurrent connections are given generously, so you don't have to worry about getting stuck doing distributed crawling.

Lastly, a word of advice: don't settle on IP quality, the time wasted by bad proxies is more expensive than money. Leave the professional work to the professionals and focus on your core business.
