How to choose a crawler proxy ip? a guide to picking one based on the strength of the target site's anti-crawl

First, the first to find out the temper of the opponents - the site anti-pickpocket strength judgment

Let's engage in crawler is like playing hide-and-seek, have to first figure out the target site security (anti-pickpocket system) patrol laws. Here to teach you a native way: first naked crawl a few times to try the water. If you just climbed 50 data on the blocked IP, it means that the security guards with themetal detectoron guard duty; and if it had lasted for a couple of hundred climbs, it might have been just the oldest man sitting in the doorway reading the newspaper.

Take a real example: an e-commerce site uses CAPTCHA + IP access frequency double insurance, which belongs to thespecial protectionThe first thing you need to do is to use a dynamic residential proxy. At this time with ordinary server room IP is like wearing slippers to war, must be on the dynamic residential proxy. Last week there was a buddy doing price comparison software, with ipipgo's dynamic IP pool, hard to a large platform of commodity data complete raking down.

 Simple anti-pickpocket strength test script
import requests
from time import sleep

url = 'Target website address'
for i in range(1,11):: response = requests.get(url)
    response = requests.get(url)
    print(f'{i}th request status code:', response.status_code)
    sleep(2)

II. Practical solutions to meet the challenges of the war

According to my experience in these years of being blocked by the website IP blocked to doubt life, to give you the entireThree-phase combat scenario::

Focusing on the toughest of the kingly sites, this is the time to have to use theguerrilla warfareipipgo's Dynamic Residential Proxy has a unique ability to set the IP alive time. For example, when you do live data monitoring, you can set a single IP survival time to 5 minutes, and with the UA random change, you can play with the security guards of the website to "change the place with one shot".

Third, hand to teach you how to choose ipipgo packages

Don't be fooled by all the fancy parameters, remember thisFool's Choice::

1. Selection for data acquisitionDynamic Residential (Enterprise Edition)The 90 million IP pool is enough for you to run wild!
2. For those who need to log in stably over a long period of time (e.g., social media operations) useStatic homesThe 500,000 IPs are all veteran actors.
3. Cross-border e-commerce with closed eyescross-border rail line2ms latency is faster than SF Express.

Previously, when configuring a TikTok solution for an MCN organization, using ipipgo'sDedicated Bandwidth + Dynamic IPCombined, the efficiency of live data collection directly doubled. Their tech guy's exact words, "This smoothness is like Dove chocolate."

Fourth, the old driver only know the anti-blocking skills

It's not enough to have a good IP, you have to be able tocombination::

- Dynamic IPs with random request intervals (don't be stupid and fix 2 seconds)
- Static IPs should simulate the trajectory of a real person
- Remember important business.IP Quality InspectionThe ipipgo backend can look at IP health in real time.

 Example of a smart request interval
import random
import time

def smart_sleep():
    delay = random.choice([1.2, 2.5, 0.8, 3.1])
    time.sleep(delay 1.5) Add a random factor to make it more natural.

V. Frequently Asked Questions QA

Q: Dynamic and static IP in the end what is the difference?
A: Dynamic IP is like a temporary actor, who is replaced after the performance; static IP is a featured actor, who can play a fixed role for a long time.

Q: How to determine the website anti-pickpocket level?
A: first naked test, see how long was sealed. 1 hour kneeling dynamic IP, can last through the night with a static IP.

Q: Does proxy IP affect the speed?
A: ipipgo's dedicated line program measured latency ≤ 50ms, more stable than your home WiFi. Last time I tested the 4K video of oil pipe, the buffering time was less than 2 seconds.

Q: Does the IP need to be changed often?
A: Dynamic IP is recommended to change automatically in 3-10 minutes, static IP can be used continuously, but do not be too wave. ipipgo background can be set up to automatically replace the strategy.

Finally, to tell the truth, the choice of proxy IP is like looking for a partner, the most important thing is to be suitable. ipipgo the thisDynamic Residential Enterprise EditionIt is true that you can beat it, especially if you are doing cross-border e-commerce, you can save a lot of trouble with their static IP program. Recently, it seems to be doing activities, new users to send 10G flow experience, specific to the official website to take a look at it.
