IP Pool: Efficient IP Proxy Pool Construction and Management Tutorial

First, hand to teach you to pick proxy IP

Choosing a proxy IP is like picking a watermelon in a vegetable market, it's easy to flip the car just by looking at the appearance. First of all, you have to look atresponsivenessIf you have a stopwatch to measure the time from sending a request to receiving a response, and it takes more than 2 seconds, you can just pass it.(med.) recovery rateSome IPs just go out of business, so it is recommended to use a script to check the survival status every hour:

import requests
def check_ip(proxy).
    res = requests.get('', 'proxy').
        res = requests.get('http://www.ipipgo.com',
                         proxies={'http': proxy},
                         timeout=5)
        return True if res.status_code == 200 else False
    return False if res.status_code == 200 else False
        return False

last seengeographic locationIf you are doing cross-border e-commerce, you have to look for the local IP of the target country, for example, if you are doing Southeast Asian market, the residential IP of Malaysia is much more reliable than the IP of the U.S. server room.

Second, the IP pool maintenance of the three great tips

1. Dynamic replenishment mechanism: Set the threshold to auto replenish, trigger the API to get new IP when the available IP is less than 20%. note that it should beStaggered withdrawal periodsDon't bunch up at the right time to get

2. Intelligent phase-out system: IPs that have failed 3 consecutive tests are directly blacked out, but don't delete them in a hurry, put them in the "Observation Area" to standby first. In some areas, the network fluctuates greatly, the IP may come back to life later.

3. Balanced distribution of trafficDon't catch an IP and use it hard, set the maximum number of requests per hour for a single IP. Here's a polling strategy to share:

from itertools import cycle
ip_pool = ['1.1.1.1:8080','2.2.2.2.2:8888']
pool_cycle = cycle(ip_pool)
def get_ip().
    return next(pool_cycle)

III. Guide to avoiding pitfalls in actual combat

Recently there is an old brother who did data collection planted, using the IP of the machine room to catch the e-commerce platform, the results triggered anti-climbing was permanently blocked. Later changed the ip ipgoDynamic Residential IP, in conjunction with these tips to bring back the dead:

- Change User-Agent per session, but don't use cold browser logos
- Important operations simulate real-life intervals, with a random wait of 3-7 seconds.
- Don't fight with CAPTCHA, it's cheaper to change IP and retry than to crack it.

IV. The tawdry operation of saving funds

Recommend trying ipipgo'sMixed packagesThe dynamic IP is responsible for high-frequency operations, and the static IP is reserved for account binding. This with the use of the cost straight down 40%. look at a real case:

A social platform operation team
Dynamic IP (standard) for daily posting: 15GB/month ≈ $115
Static IP for account login: 5 IPs ≈ $175
Total cost saved 210 bucks over purely using a static IP

V. QA First Aid Kit

Q: How big should the IP pool be to be sufficient?
A: 200 is enough for daily activities of 1000 times or less, and 50 for every 500 times of expansion. But don't blindly pile up the quantity, quality is more important

Q: How is the frequency of testing determined?
A: Sweep one round every 15 minutes during peak business hours and measure once every 2 hours during idle hours. Abnormal IPs are found and suspended immediately

Q: How do I choose for my enterprise level needs?
A: Directly on ipipgo's customized program, they can according to the business scenarios with different regions of the IP portfolio, than self-built to save a lot of effort!

VI. Why ipipgo

After 3 years of using agency services, this one does have something:
- TK LineDoing short video operations without dropping the ball
- Dedicated Static IPSupports binding device MAC addresses
- I called customer service at 2:00 a.m. and got a second response.
- The cheapest package is only 25 cents a day, cheaper than a bottle of water.

Beginners are advised to start withDynamic residential (standard)Test the waters, 7 days no reason to refund this is very real. Business users remember to open a dedicated channel, the speed can be faster than 30%. Recently, it seems to be doing activities, renewals can also be discounted, specifically to ask their customer service.
