IP Proxy Pool Construction: Building and Maintaining a Highly Available IP Proxy Pool Solution

Hands on with building a reliable agent pool

Brothers engaged in data capture understand that the proxy IP fails twice a day than the aunt is still on time. Today, we will nag how to build a resistant IP pool, focusing on the pits that are easy to step on.

First, catching IP is like fishing, you have to choose the right fish pond.

Looking for a free proxy site? Don't be silly! Nine times out of ten those public IPs are used badly by others. Why don't you just go to a professional service provider likeipipgo's dynamic residential packages, $7+ 1G lasts for days, and the key is reliable IP quality.

 Sample API for grabbing ipipgo with Python
import requests

api_url = "https://api.ipipgo.com/get_proxy"
params = {
    "key": "Your key",
    "count": 50,
    "protocol": "socks5"
}
response = requests.get(api_url, params=params)
print(response.json())

Second, the inspection link can not be saved

Don't rush the newly captured IP, go through three levels first:

Suggest getting an auto-detection script that runs every hour. IPs found to be lagging are directly kicked out of the group chat.

Third, raising an IP is harder than finding a date

Maintaining the pool has to be strategic:

• Dynamic IPs as vanguard (good for short-term assignments)
• Static IPs as a mainstay (recommended)ipipgo's $35 package(long-term stability)
• Automatic replenishment of stock at 3:00 a.m.

Focus on the scheduling algorithm, do not organize those fancy polling, according to the IP response speed dynamic allocation is reliable. Take a chestnut:

 Simple version of the scheduler
from collections import deque

class ProxyPool.
    def __init__(self).
        self.fast_queue = deque() Fast response IPs
        self.slow_queue = deque() slow IPs

    def get_proxy(self).
        if self.fast_queue.
            return self.fast_queue.popleft()
        return self.slow_queue.popleft()

IV. Practical experience in stepping on potholes

Last year, I helped a friend to engage in e-commerce price monitoring, and encountered an evil thing: using a certain agent is always blocked, and changed theipipgo's TK lineImmediately resolved. Then I realized that some service providers' IP segments had been focused on long ago.

Another counter-crawling tip: don't catch a site gripping hard, spread the requests to different IPs. it's recommended to distribute them in this ratio:

• 50% request with normal dynamic IP
• Static Residential IP for 30%
• 20% with a dedicated cross-border line (e.g.International lines for ipipgo)

V. Frequently Asked Questions QA

Q: What should I do if the IPs in the proxy pool keep failing?
A: three directions of investigation: 1. whether the detection interval is too long 2. whether to trigger the anti-climbing rules 3. change to a higher quality service provider (such as static residential IP)

Q: What if I need both socks5 and http proxy?
A: Directly select a vendor that supports multi-protocols, like theipipgoJust support HTTP/HTTPS/Socks5 at the same time, no need to switch back and forth.

Q: What can small companies do if they can't afford to use a high-priced agent?
A: Flexibility with packages, dynamic residential ($7.67/GB) for daily use and static IP for mission-critical. ipipgo can also customize the plan for businesses that are just starting out.

VI. Service provider selection doorway

One last industry secret: look for providers that don't have their own dial-up servers. The ones like ipipgo that work directly with carriers can have IP survival time up to 3 times longer than ordinary service providers. Especially their enterprise version of the dynamic package, although more expensive ($ 9.47 / GB), but suitable for projects that need stability.

Remember, a good proxy pool is not a heap of IP counts, it's aQuality + Scheduling StrategyThe combination of. In the beginning, it is recommended to use ready-made services first, and then consider self-build when the technology matures, saving time and effort without any trouble.
