Free Proxy Hosting List: Test Proxy IP Collection

Are free agents reliable or not? The actual test experience to share

Finding a free agent online is like picking fruit in a food market - it looks shiny, and the bite may sour your teeth. Recently, I helped a friend to do a data collection project and tested 37 free agent sources.Fewer than 10% will work.I have a Russian proxy IP. There is a Russian proxy IP, the test shows connectivity, the actual use of latency up to 8 seconds, slower than a snail crawl.

The three pits of free agency, a must-see for newbies

1. lit. short-lived ghost type: IP lists just collected in the morning, and then a collective strike in the afternoon
2. tortoise speedster: It takes half a minute to load the first page of Baidu.
3. a booby-trap: Certain IPs can secretly record your access data.

Here's a self-test tip: Use Python to quickly verify that the proxy is alive (don't use online testing tools directly, some will steal IPs)

import requests

proxy = {"http": "123.45.67.89:8080"}
try: response = requests.get('', proxies=proxy, timeout=5)
    response = requests.get('http://httpbin.org/ip', proxies=proxy, timeout=5)
    print("Available! Real IP:", response.json()['origin'])
except.
    print("This proxy should go to the trash")

Why do veterans use paid proxies? Doing the math.

The last time I used ipipgo's residential agent for a crawler project.7 days in a row without being blockedThe key is that their IPs are automatically changed at regular intervals, saving you the trouble of having to toss and maintain them yourself.

Hands on with choosing an agent service

Remember these three.Gold Indicator::
1. Look at the IP type: to have a mix of data center + residential + mobile like ipipgo
2. Measurement of response speed: direct passes over 1 second
3. Check protocol support: at least support HTTP/HTTPS/Socks5
