Proxy IP Anti-Blocking Principle: In-depth Understanding of Anti-Crawl Mechanisms and Proxy Countermeasure Strategies

Proxy IP anti-blocking combat manual: hand to teach you to avoid the anti-climbing minefield

All of you do data collection friends, surely have experienced the bad thing of IP blocked. Today we will break open the crumbs to talk about, the platform in the end how to find out that you used a proxy, and how to use ipipgo family proxy service to see the trick.

First, the platform anti-climbing three axes, see through the set of good breakthroughs

The platform's anti-crawling system is now like a security checker, screening abnormal traffic in three main dimensions:

1. IP anomaly detection

If the same IP is frantically requested dozens of times in a minute, any fool knows there's a problem. However, some platforms are even more sneaky and will look at the IP's geographic drift - for example, in the morning in Beijing, and then in the afternoon instantly to New York, which is even more outrageous than Superman.

 Example of error: Single IP continuous request
for i in range(100).
    requests.get('https://xxx.com', proxies={'http':'1.1.1.1:8080'})

 Correct posture: dynamically rotate the IP pool
proxy_pool = ipipgo.get_proxies(type='dynamic') call ipipgo's dynamic IP pool
for url in target_list.
    proxy = random.choice(proxy_pool)
    requests.get(url, proxies=proxy)

2. Fingerprint signature recognition

Browser fingerprinting nowadays recognizes 200+ feature parameters. For example, if your User-Agent in the request header is Chrome, but the screen resolution is a cell phone size, it's wearing out.

3. Behavioral pattern analysis

Normal people will not brush the web page for 8 hours continuously at 3 am, nor will they accurately visit at a rhythm of 3 times per second. The platform will count the mouse movement trajectory, click interval these details, robot operation is too regular will be easy to reveal.

Second, choose the right type of agent, better than half of the anti-blocking secret book

The two main treasures of ipipgo must be enlisted here:

For example, if you want to do price monitoring, you need to use a dynamic proxy to capture hundreds of product pages in a minute; but if you want to keep a social media account, you need to use a static proxy to keep a fixed IP address so that you won't be penalized for abnormal logins.

Third, the old drivers are using anti-blocking skills

Here's a few tawdry maneuvers that have been tested to work:

1. Traffic camouflage

Randomly insert garbage parameters into requests to make each request look different:

params = {
    'keyword': 'cellphone',
    'timestamp': str(int(time.time()1000)),
    'random_str': ''.join(random.sample(string.ascii_letters,5))
}

2. Simulation of work schedules

Set random delays, don't let the program act like a perpetual motion machine:

time.sleep(random.uniform(1.2,4.8)) is more natural than fixing 3 seconds

3. Device fingerprint obfuscation

Use ipipgo's browser fingerprinting service to automatically generate real device parameters:

headers = ipipgo.generate_headers(device_type='mobile')

IV. First aid kit for common problems

Q: What should I do if I use a proxy and still get blocked?
A: First check whether the IP purity is not enough, change ipipgo static residential agent to try. If it does not work, remember to adjust the request frequency, plus random delay.

Q: How to choose between dynamic and static proxies?
A: High-frequency acquisition choose dynamic (standard package), need to choose static fixed IP. Enterprise-level business directly on the dynamic (enterprise package), there are exclusive IP pool more stable.

Q: What can I do if the delay is too high for overseas business?
A: With ipipgo's cross-border line, the measured latency can be pressed to 2ms. their TikTok solution to do the live broadcast are not stuck, the ordinary collection is even less.

The last thing I want to say is that anti-blocking is a long-lasting battle. Choose the right proxy service provider will be half successful, ipipgo's dynamic residential proxy I used for half a year, with the above tips, the collection success rate can be stabilized at 99% above. Especially their city-level positioning function, do regional data comparison is good. Newbies are advised to buy a package that is billed according to the flow rate, so that they can use as much as they want without wasting it.
