Proxy IP Dataset Construction: A Technical Guide to Proxy Dataset Construction

How to save proxy IP datasets? Teach you how to do the whole job!

Older drivers who work with data know that a reliable proxy IP library is the thing to eat. Let's get down to the nitty-gritty today and teach you how to use theLocal methods + black technologySave a hardcore proxy pool. Let's start with a misconception, don't think you can just grab a list of free IPs and have it work, eight out of ten of those contraptions are just for show.

We've practiced the routine in three steps:
1. First take the crawler as a sieve, the whole network to fish the first wave of raw IP
2. Get on the machine and verify survival rates automatically, don't be soft.
3. Regularly change the blood of the IP pool, just like the fish have to change the water.

 Take a Python chestnut for IP authentication
import requests
from concurrent.futures import ThreadPoolExecutor

def check_proxy(proxy).
    try: resp = requests.get('').
        resp = requests.get('https://ipipgo.com/check',
                          proxies={'http': proxy}, timeout=5))
                          timeout=5)
        return True if resp.status_code == 200 else False
    return False if resp.status_code == 200 else False
        return False

 Open 20 threads for concurrent validation
with ThreadPoolExecutor(20) as exe: results = exe.map(check_proxy, ip_list)
    results = exe.map(check_proxy, ip_list)

Validating the tawdry operation of the session

Just being able to connect is not the end of the story, it depends on whether the IP carries the build or not. Focus on three indicators:
- Speed of response: more than 3 seconds for direct throws
- Stability: 10 consecutive requests, more than 2 passes if the chain is dropped
- Geographic location: some businesses have mandatory location requirements

Here's a good one, from ipipgo.TK LineThe IPs are all genuine local carriers' resources. Their family IP are serious local operators resources, measuring geographic location accurate a batch. The key time can save a lot of things, especially do cross-border e-commerce friends have to take notes.

A practical guide to avoiding the pit

Seen too many people fall into these pits:
1. Greedy use of free agents, the result of business data was intercepted
2. not pay attention to the IP cooling time, the good IP to burn waste
3. No request header camouflage, the website will recognize it in minutes.

Here's a wild idea: use ipipgo'sDynamic Residential PackageThe first time I saw this, it was a very good thing that I was able to get it to work, because it was a very good thing that I was able to get it to work. Especially do data collection brother, remember to adjust the request interval randomly, do not whole with the robot like law.

question-and-answer session

Q: How often is it appropriate to update the dataset?
A: Look at the volume of business! We recommend hourly updates for a million daily activities, and weekly blood changes for small businesses. ipipgo's API can set up automatic extraction intervals, so it's easy to save time.

Q: What should I do if I keep getting my IP blocked?
A: three brochures: 1. change high-quality static IP 2. reduce the frequency of requests 3. on the browser fingerprint camouflage. Budget enough to directly on the ipipgoEnterprise Package, $9+ 1G, survival rate can go to 90% and up.

Q: How to choose between dynamic and static IP?
A: Grab data with dynamic, do long-term business with static. ipipgo's static residential IP 35 dollars a month, suitable for raising the number, hanging these need to fix the identity of the scene.

Tell me something from the heart.

Proxy IP this line of deep water, seen too many people trying to save trouble to fall. Remember the three principles:
1. Don't cost out on IP quality
2. No corners to be cut in the validation process
3. Business scenarios determine technology selection

As a final plug, if you're struggling to toss it yourself, just nag the tech guy at ipipgo. Their1v1 Customized SolutionsIndeed can save a lot of things, especially to do cross-border business, dedicated resources are not covered. But then again, the specific choice of what package also depends on the volume of their own business, the volume of remember to cut the price, can save a little is a little.
