Proxy Scanner: Proxy IP Quality Scanning Tool

Hands down, I'll teach you to pick out a good proxy IP.

Friends engaged in network crawlers know that the quality of the proxy IP directly determines the success or failure of the business. Recently found an interesting phenomenon: many people in the use of the failure of the proxy is not aware of, until the data crawl suddenly plummeted before reacting. Today we will teach you to useBuild Your Own ScannerWe're here to check the quality of our agents, and we recommend our ownipipgoServices.

Do-It-Yourself Inspection Tools

Don't be intimidated by the word "scanner", in fact, writing a basic inspection script in Python is only 20 lines of code. At its core, it checks three metrics:responsiveness,availability rate,Degree of anonymityLet's look at a simple example. Let's look at a simple example:

import requests
from concurrent.futures import ThreadPoolExecutor

def check_proxy(proxy)::
    start = time.time().
        start = time.time()
        resp = requests.get('http://httpbin.org/ip',
                          proxies={'http': proxy}, timeout=5)
                          timeout=5)
        cost_time = round(time.time()-start,2)
        if resp.json()['origin'] == proxy.split(':')[0]::
            return False transparent proxy
        return (True, cost_time)
    except.
        return False

 Example usage
proxy_list = ['1.1.1.1:80','2.2.2.2:3128']
with ThreadPoolExecutor(10) as executor.
    results = executor.map(check_proxy, proxy_list)

This script quickly detects if an agent is alive or not, and also recognizes theTransparent Agent(the kind that exposes the real IP). It is recommended to set the timeout at 3-5 seconds, too short is easy to mistakenly kill quality proxies.

What tests are used by the pros

You really need to get professional proxy scanning, you have to pay attention to these details:

Special note: Don't trust those tools that claim to have a detection success rate of 100% in real scenariosAble to have 85% or more availableIt's a quality agent. Our ownipipgoThe dynamic residential agent's measured availability has been maintained at more than 92% for a long time, and there was one test that did not drop for 48 hours in a row.

Why recommend a professional service provider

The pain point of maintaining your own agent pool is known to anyone who uses it:

• High maintenance costs (at least 2 hours of maintenance per day)
• IP purity is difficult to ensure (often mixed in with banned IPs)
• Difficulty in responding to sudden demands (blinded by the need for a large number of IPs at a moment's notice)

expense or outlayipipgoThis type of professional service provider is the equivalent of hiring a 24-hour housekeeper. Their homeIntelligent RoutingThe function is very interesting, can automatically switch the optimal line. The last time I helped a customer to do price comparison crawler, with the ordinary proxy success rate of only 67%, cut to ipipgo directly soar to 91%.

Frequently Asked Questions

Q: Do free proxies work?
A: temporary test can be, long-term use of absolute blood loss. Seen the most tragic case: using free agents to climb the data, the results of the target site to the entire IP segment black, change the paid agent can not be saved.

Q: How is the frequency of testing determined?
A: Sweep every 15 minutes during peak business hours and once every 2 hours on weekdays. If it is a stable service like ipipgo, sweeping 3 times a day is enough.

Q: How do I choose an enterprise level program?
A: Directly onipipgo Enterprise, support customized geographic distribution. There is a friend who does overseas e-commerce, specifically customized the residential IP of the three major cities in the United States, the conversion rate is directly doubled.

A final rant: testing tools are only a means to an end, the key is still tosource control. Instead of tossing around detection scripts every day, why not just go to theipipgoof ready-made programs. They recently came out with a newdynamic mixed dialing packageIt's quite interesting that it supports auto-matching of agent types by business type, which is much more hassle-free than tossing it yourself.
