Crawler Proxy Pool: Crawler-specific Proxy Pool Management System

Why do crawlers have to use proxy pools?

Recently there is a buddy to do data collection, just started three days on the target site blocked IP. frankly, now the site are very fine, found abnormal traffic directly to you choke off. This time we have to rely on the proxy pool toRotation of different IP addresses, making the site think it's being visited by a bunch of regular users.

Take a real example: suppose you want to capture the price of the e-commerce platform, single use their own IP request hundreds of times per hour, I'm sure to be recognized as a crawler. If you use a proxy pool, each request for a different region of the IP, like hiring 200 people in different cities to help you check the price, the safety factor can be doubled several times.

Build your own agent pool or use an off-the-shelf one?

Let's start with the conclusion:It is more cost-effective for small and medium-sized projects to buy services directlyThe first thing you need to do is to get a proxy pool on your own. To get your own proxy pool you have to rent servers, maintain IP libraries, deal with CAPTCHAs, and you can lose a handful of hair just debugging proxy stability. Take ipipgo's dynamic residential package, you can use 1GB of traffic for more than 7 bucks, which is a lot less hassle than maintaining it yourself.

Practical: get a proxy pool with ipipgo

Here's a Python example given to extract IPs using their API:

import requests

def get_proxy(): api_url =
    api_url = "https://api.ipipgo.com/get?format=json"
    resp = requests.get(api_url).json()
    return f"{resp['protocol']}://{resp['ip']}:{resp['port']}"

 Example of use
proxy = get_proxy()
print(f "Currently using proxy: {proxy}")

pay attention toGet a timed task to refresh the IP poolIt is recommended to change IPs every 5-10 minutes. ipipgo's client comes with an intelligent switching function, which saves you a lot of work compared to managing it manually.

Guide to avoiding the pit: 5 common mistakes made by newbies

1. Greedy to use free proxies: those so-called free IP, nine out of ten can not be used, but also may be anti-climbing system marking!
2. No request interval: even if the IP is changed, the continuous frantic request will still be exposed.
3. Ignore the protocol type: some sites only recognize the HTTP protocol, using Socks5 will be recognized instead!
4. Forget to clean up the invalid IP: it is recommended to automatically clean up the IP records 24 hours ago in the early morning every day.
5. Single-geography IP pileup: choose more IP segments in several different cities, do not use all of Shanghai or Beijing.

QA Time: Frequently Asked Questions

Q: Does the proxy pool need to be maintained?
A: Required! We recommend checking IP availability weekly, below 80% it's time to switch providers or packages.

Q: How do I test if the agent is valid?
A: Get a validation script and visit https://httpbin.org/ip看返回的IP对不对 periodically.

Q: How to choose between dynamic and static IP?
A: If you need to log in for a long time, choose a static IP (such as keeping logged in), and use dynamic for ordinary collection to be more secure.

When it comes to reliable proxy service providers can save half the effort. Support like ipipgoCustomizedIt is especially suitable for projects that require special protocols or geographical distribution. I have tested their TK line, and the success rate of collecting data from specific platforms can reach more than 95%, which is indeed much stronger than that of general-purpose proxies.

Price, personal projects choose the standard version of the dynamic residential enough to use. If the enterprise-level projects, it is recommended to go directly to the enterprise version of the package, more than 9 yuan 1G traffic with exclusive channel, better stability. Remember, proxy IP this thing is a penny for a penny, do not key in the key business on the budget of a few dollars.
