Free Agent Website: Free Agent Resource Platform

Are free proxy sites reliable or not? Here's a guide to preventing pitfalls

Online casually search "free proxy", jumped out of hundreds of websites claiming to provide free IP resources. But those who have used it know that these IP ten in eight can not connect, it is not easy to connect to the slow speed to doubt life. Let's peel off the bottom of these free agents today, teach you how to identify real and fake wool.

Three common pitfalls of free agents

The first pit: IP survival time is shorter than goldfish. The IPs that worked yesterday are collectively lost if you try again today. A friend doing e-commerce used a free proxy to catch the price of competing products, and the result was that it took 20 IPs in half an hour to catch a page of data.

The second pit: Internet speed is comparable to a snail's crawlThe following are some of the reasons why I've been using this site. Tested the IP of a free website, the highest download speed of 12KB/s, load a common web page are half a minute, this efficiency is not as good as manual hand-copying.

Pit 3: Hidden Security RisksThe first time I saw this is when I was a student at the University of California at Berkeley. Last year, a company with a free agent to do crawlers, the results of the background data was counterpicked, and later found out that the proxy server is stealing data. The sky will not fall pie, what is free for you to use?

Don't use free proxies in these scenarios

1. need to run for a long time the task: such as automation scripts, free agents in the middle of the chain can make you lose all your efforts!

2. Handling sensitive data: account passwords, payment information, the use of free agents is equal to the naked run!

3. High-frequency access needs: a brother who does SEO monitoring, using free proxy to check rankings by the target site blocked the local IP

Hands on testing of agent quality

Prepare a Python script to test proxy availability (don't be afraid, the code is simple):

import requests

proxy = {"http": "http://123.45.67.89:8080"}
try: resp = requests.get('', proxies=proxy, timeout=5)
    resp = requests.get('http://httpbin.org/ip', proxies=proxy, timeout=5)
    print(f "Currently using IP: {resp.json()['origin']}")
except.
    print("Proxy has failed!")

After running this script, you can see whether the current proxy is in effect. But note that being able to connect doesn't mean that it works, it also depends on the performance of the actual business scenario.

QA time: what you might want to ask

Q: How long will the free agent last?
A: Like opening a blind box, you can use it for a few hours with luck, most of them can't live more than 10 minutes. To be stable in the long run you still have to use a professional service provider like ipipgo.

Q: Is there a compromise?
A: ipipgo offers pay-as-you-go packages, using as much as you can. It is more reliable than free agents and more flexible than monthly packages, especially suitable for small and medium-sized projects.

Q: How can I prevent my IP from being blocked?
A: ipipgo's dynamic rotation function can automatically switch IPs, and with their intelligent routing algorithm, the blocking rate can be reduced by more than 70%.

In the end, the free proxy is like a public restroom, emergency use is fine, long-term dependence will be a problem. Really want to do business, or have to use ipipgo such serious service providers. After all, time is money, in order to save a little agent fee to delay the main event, that is really a big loss.
