Cheap Shared Proxy: Economical Multi-Player IP Sharing

Do cheap shared proxies work or not?

Recently, people always ask me: "Lao Zhang, those ridiculously cheap sharing agents are reliable?" This thing is like buying a cell phone at Spelling Eve - some people flip the car and some people really smell good. Let's start with the conclusion:The right scenario is a godsend, the wrong one is a potholeThe first thing we need to do is to find out what the best way to do this is. We have to figure out which situations are best suited for this kind of thing where you can buy thousands of IPs for a couple of dollars.

Shared Proxy Principles in Three Minutes

Imagine a shared proxy like a carpooling service. 5 people (5 users) in one car, sharing the same car (same IP). ipipgo's shared pool is updated with tens of thousands of IPs every day, and each IP serves up to 20 users at the same time. The biggest benefit of this model is:Prices can be as low as 1/10th of the price of an exclusive agent., but the response time will be about 0.3 seconds slower than that of an exclusive share.

Teach you the right way to open it

In the case of the Python crawler, for example, there are two things to pay special attention to with ipipgo's shared proxy:timeout settingrespond in singingretry with an exception. Don't be stupid and use the default parameters, here's a real-world configuration:

import requests
from retrying import retry

@retry(stop_max_attempt_number=3)
def crawl(url).
    proxies = {
        "http": "http://用户名:密码@gateway.ipipgo.com:9020",
        "https": "http://用户名:密码@gateway.ipipgo.com:9020"
    }
     Important! Set a reasonable timeout
    response = requests.get(url, proxies=proxies, timeout=(3, 7))
    return response.text

 It is recommended to change IPs for each request (turn on auto-rotation on the account management page)

Notice in the code thetimeout=(3,7)This means that it takes 3 seconds to establish a connection and 7 seconds to transfer data. A lot of newbies planted in not set timeout, the program is stuck do not know.

A guide to avoiding the pitfalls of the five major rollover sites

1. CAPTCHA suddenly spikes: Possible IP abuse by multiple people, immediately change the regional pool in the ipipgo background
2. Some sites won't log in.: check if UA detection is triggered, remember to randomly generate User-Agent
3. It's a snail's pace.: Avoid the evening peak (20:00-23:00), or cut to the business district IP band
4. The connection keeps dropping.: Set the number of retries to 3-5, don't use a single attempt
5. Account blocked for no apparent reason: Don't log in to multiple accounts at the same time from the same IP, use ipipgo's session hold feature!

question-and-answer session

Q: Will the shared IP leak my data?
A: regular service providers like ipipgo are HTTPS encrypted transmission, more than 10 times safer than using a free proxy. But don't use it for payment operations!

Q：Why is the IP display not accurate sometimes?
A: This is a common problem with shared proxies, there is a delay in updating the IP database. If you need precise positioning, it is recommended to use exclusive residential proxy, the error of ipipgo's business package is not more than 3 kilometers.

Q: How do you ensure stability during peak times?
A: Remember this mnemonic: the early bird gets the worm (07:00-09:00 is the fastest), work smoother on weekends, and avoid e-commerce promotion days like Double 11 618.

A final heartfelt word:Choosing a shared proxy is like finding a dateDon't just look at the price, look at the after-sales service. Last time I tested a pheasant service provider, IP failure for three days no one cared. On the other hand, ipipgo's customer service, two o'clock in the morning is still online to change the IP, this money is worth it.
