Free Proxy IP Resources: Free Proxy IP Tests Updated Daily

Free proxy IP in the end reliable or not? First look at the real test results

Recently, a lot of friends asked me, those free proxy IP on the Internet can be used? This thing must be broken up to say. I dedicated three days to test more than a dozen free proxy sources, and found that60%'s address won't connect.The speed of half of those who can connect is as slow as a snail's pace. To cite a chestnut, there is a so-called "high-speed" proxy, access to Baidu actually want 8 seconds!

However, free resources are not completely useless, suitable for temporary emergencies. For example, if you want to check a data and do not want to expose their IP, you can use it temporarily. But if you are engaged in crawling or batch operation, I advise you to save time--Free agents are as stable as the weather in June.The

Hands-on teaching you to test the validity of proxy IP

Testing the proxy is actually very simple, just make a Python script. Pay attention to the timeout settings in this code, more than 3 seconds directly pass:

import requests

proxy = {"http": "123.45.67.89:8080", "https": "123.45.67.89:8080"}
try: response = requests.get("")
    response = requests.get("http://httpbin.org/ip", proxies=proxy, timeout=3)
    print(f "Valid proxy! Response speed: {response.elapsed.total_seconds():.2f} seconds")
except.
    print("This proxy is dead, move on to the next one.")

Here's the kicker: when testing remember toChange a few more target sitesIt's a good thing that you can't access the website. Some proxies can access site A but not site B. It has to do with the site's anti-crawl mechanism. I usually measure these three:
1. Baidu (basic connectivity)
2. Microblogging (with cookie validation)
3. Government-type websites (high security)

Why do the pros use ipipgo?

Anyone who has used a free proxy knows that the experience is like opening a blind box. Later, I switched toipipgoof paid services, the good guys open up new worlds straight away! Let's say a few real ones:
- Average response time <800ms (average 3 seconds + for free)
- Automatically update the IP pool on a daily basis
- Support for node selection by city
- 7×24 hours technical customer service

theirIntelligent Route SwitchingIt is really fragrant. Before doing data collection, set up a failure to automatically change IP, the program can run all night. If you use a free proxy, you will be given the whole thing in the middle of the night.
