Buying Datasets: Proxy IP for Large-Scale Data Collection

These days, doing data collection without a proxy IP is like running with a limp.

Last week, Lao Zhang's company was just blocked by the IP of the target website, and the whole crawler project was directly paralyzed. This is too common in the circle, now the website anti-climbing mechanism is more and more refined, rely solely on an IP hard just, like a face to catch a bullet - death through and through. This time we have to rely on proxy IP toDistributed fire, as if putting a different vest on each data request.

Let's take a real example: to do e-commerce price comparison, you have to keep an eye on the price changes 24 hours a day, right? With their own IP continuous access, less than two hours quasi-recognized. But if you use ipipgoDynamic Residential AgentsIf a real user's network environment is changed for each request, the site simply can't tell if it's a real person or a program that's accessing it.

import requests
from ipipgo import get_proxy Here we use ipipgo's SDK to get the proxy.

def fetch_data(url).
    proxy = get_proxy(type='residential') choose residential proxy to be more invisible
    proxies = {
        "http": f "http://{proxy['username']}:{proxy['password']}@{proxy['server']}",
        "https": f "http://{proxy['username']}:{proxy['password']}@{proxy['server']}"
    }
    try.
        response = requests.get(url, proxies=proxies, timeout=10)
        return response.text
    except Exception as e.
        print(f "Failed to collect and automatically switch IPs: {str(e)}")
        return fetch_data(url) Automatically switch to new proxy

There are three main hits to look for when choosing a proxy IP

Agent services on the market are a mixed bag, remember these threelife-saving indicator::

Focusing on residential proxies, ipipgo's residential IP pool in the90% are all home broadband, the capture is no different from a real person surfing the web. The last time I helped a client to capture real estate information, it ran for a month without triggering the verification, which is the power of the real residential agent.

White guide to avoid the pit: these mines must not step on

1. Don't buy shared IPs on the cheap: Some service providers sell 1 IP to 10 families, and the result is a collective block. ipipgo is assigned to each session.Exclusive accessEquivalent to chartered VIP access

2. Pay attention to IP purity: Send a request to the proxy IP to see if the X-Forwarded-For header returned is the real IP. ipipgo's proxy willAutomatically erases these tracesI don't think it's a good idea to give away your real identity.

3. Be flexible with your rotation strategy: Don't be silly to change IP every minute, to adjust dynamically according to the response of the target site. For example, if you encounter a 403 error, switch immediately, and keep the normal state for 5 minutes before changing. ipipgo'sIntelligent switching modeCan automatically learn the law of website anti-crawl

The QA session you care most about

Q: What should I do if my proxy IP is slow?
A: Choose the node that is close to the geographic location, ipipgo supports filtering by city. For example, the collection of local websites in Shanghai, choose the agent of the Shanghai server room, the delay can be controlled within 50ms!

Q: How do I break the CAPTCHA when I encounter it?
A: ipipgo'sHighly anonymous agents+ Request header camouflage duo. Measured with Chrome fingerprinting emulation, the CAPTCHA trigger rate can be reduced by 70%

Q: How can I tell if a proxy is in effect?
A: Visit https://ip.ipipgo.com/check this test page to see the current proxy IP and geolocation used. It is recommended to run this check before collection

Tell the truth.

I've seen too many people trying to save money by using free proxies, but the result is that they don't get the data but get into trouble. Professional things are still left to professional tools, ipipgo'sCommercial level agency servicesWith request failure automatic retry, IP blacklist filtering these practical functions. Recently they are engaged in activities, new users to send 10G flow, fill in the registration [DATA2023] can also lead to an additional 5-day trial period, the wool is not woolgathering white not woolgathering.
