Dynamic ip proxy pool: dynamic ip proxy pool building methods

What's the point of having a dynamic IP pool?

What are you most afraid of when doing data collection? IP blocking! Ordinary fixed IP is like going to the supermarket to steal candy with the same face, sooner or later the security guard will catch you. Dynamic IP pool is equivalent to changing different costumes every day to purchase, not only can get the job done, but also let the website system can not feel the pattern.

To cite a real case: last year, there is a small team of e-commerce price comparison, with a fixed IP to capture data for three days to be blocked. Then changed the dynamic residential IP pool, every day automatically switch 500 + different regions of the IP, the success rate of data collection directly from 40% soared to 92%. this thing on the need for high-frequency operation of the business is a life-saving straw.

What do I need to prepare to build my own pool?

Let's first straighten out the four core components:IP sources, authentication modules, scheduling systems, log monitoring. Don't be intimidated by the terminology, it's actually similar to fish farming, you have to have good fry (to stabilize the IP source), regular water changes (to verify survival), proper feeding (scheduling strategy), and observing the water quality (to monitor the log).

Focus on the pitfall of IP sources. There are three common paths on the market:

The dynamic residential package of ipipgo, which is more than 7 dollars for a 1G traffic jump, supports HTTP/HTTPS/Socks5 three protocols. The point is that their IP pool is automatically updated every day, unlike some service providers to take the IP room to fool people.

Teach you how to build a shelf by hand

In Python, for example, the entire simple version of dynamic pooling is a three-step process:

 Step 1: Use ipipgo's API to get an IP pool
import requests
def get_proxies():
    api_url = "https://api.ipipgo.com/dynamic?key=你的密钥"
    resp = requests.get(api_url)
    return [f"{proto}://{ip}:{port}" for proto,ip,port in resp.json()]

 Step 2: Survival detection (key!)
def check_alive(proxy):
    try.
        test_url = 'http://httpbin.org/ip'
        return requests.get(test_url, proxies={'http': proxy}, timeout=5).ok
    except: test_url = '' return requests.get(test_url)
        return False

 Step 3: Scheduling Module
class ProxyPool.
    def __init__(self).
        self.valid_proxies = []

    def refresh(self):
        new_list = [p for p in get_proxies() if check_alive(p)]
        self.valid_proxies = list(set(new_list + self.valid_proxies))[:100] keep latest 100

Note that the timeout parameter in the code should not be set too large, more than 5 seconds of the agent is basically useless. It is recommended to automatically refresh every half hour, and speed up the updating tempo when encountering frequent CAPTCHA appearances.

Common Pitfalls Fact Sheet

1. IP purity issues: Once the customer used a certain airport IP, the result of the target site directly return 419 error. Later change ipipgo TK line to solve, this special line of business on the blocking strategy has targeted optimization!

2. Protocol mismatchA forum must be accessed with socks5 protocol, http proxy all pounced on the street. It is recommended to confirm the type of protocol supported by the service provider when purchasing.

3. obsessive-compulsive geographic selection (OGGS)Don't insist on local IPs, sometimes it's better to use the next province. ipipgo's node selection supports filtering by AS number, a feature that many families don't have.

QA First Aid Kit

Q: How to choose between dynamic and static IP?
Look at the business scenario! Need to maintain long-term sessions (such as hang games) with static, short-term high-frequency requests (data collection) with dynamic. ipipgo's static residential packages starting at $ 35 / month, suitable for businesses that require a fixed identity!

Q: What should I do if the proxy pool is slow?
① check whether the mix of different regional IP ② switch protocols to try ③ contact the service provider to open a cross-border line. Last time there is an overseas e-commerce customers, cut to ipipgo cross-border line after the delay from 800ms down to 200ms!

Q: How do I detect if an agent is exposed?
It is recommended to use https://ipipgo.com/check这个页面, which can show the degree of anonymity of the current IP. Don't use those testing sites that show detailed information, it is easy to leak fingerprints

Tips for choosing a service provider

Bloody experience of having used seven or eight vendors:

• Depends on whether it supports customization on demand (ipipgo does this well)
• Focus on IP replacement success rate during testing
• Don't believe in unlimited traffic packages. Serious business is billed on demand.
• Customer service responsiveness is more important than price, and you know when something goes wrong!

Speaking of dynamic IP pools is not something that can be done once and for all. You have to adjust the strategy according to the anti-climbing mechanism of the target website and cooperate with the technical support of the service provider in order to get twice the result with half the effort. Our family ipipgo recently on the new intelligent scheduling API, according to the type of business can automatically match the IP pool strategy, need to try their enterprise version of the package.
