Web Crawl IP Rotation: Automatic IP Switching for Anti-Blocking Solutions

Why are IPs always blocked? Let's get to the bottom of it.

The old iron engaged in data collection should have encountered this hurdle - the target site suddenly blocked your IP. This is just like when you go to the supermarket and try to eat at the same counter 20 times in a row, the security guards will not chase you away. This is the reason why the website protection system.High-frequency access from a single IP will definitely trigger the blocking mechanism.The first thing you need to do is to change your IP address to the right IP address. Some sites are more ruthless, directly on the man-machine verification, this time to change the IP is the most direct breakthrough move.

Too much trouble to change IP manually? Try this automated solution

Don't use what reboot the router to change the IP of the earth's way, that efficiency is slower than a snail crawl. Here's a tip for you:Using proxy IP pools + auto switching scriptsThe principle is simple. The principle is simply to prepare dozens of hundreds of IP, like a guerrilla war in turn with. Here focus on ipipgo's dynamic IP pool, their IP survival rate can be 95% or more, the actual test run data business special savings.

import requests
from itertools import cycle

 Get the latest IP pools from ipipgo
def get_ipipgo_ips():
    api_url = "https://api.ipipgo.com/v1/getips?num=50"
    response = requests.get(api_url)
    return [f"{ip['ip']}:{ip['port']}" for ip in response.json()]

 Create the IP cycler
ip_pool = cycle(get_ipipgo_ips())

 Request function with autoswitching
def smart_request(url):
    for _ in range(3): retry at most 3 times
        current_ip = next(ip_pool)
        proxies = {
            "http": f "http://{current_ip}",
            "https": f "http://{current_ip}"
        }
        try: resp = requests.get(url)
            resp = requests.get(url, proxies=proxies, timeout=10)
            if resp.status_code == 200: return resp.
                return resp.text
        except Exception as e: print(f "IP {current_ip}")
            print(f "IP {current_ip} request failed, auto switching...")
    return None

Five anti-blocking practical skills personally tested effective

1. IP quality over quantityThe IP pool of ipipgo has been used by our team for more than half a year, and we basically haven't encountered any cases of banning.
2. Switching rhythms should be randomized: Don't change it every 5 minutes, change it to 3-7 minutes random interval, so that the website can't feel the pattern.
3. The request header remembers to disguise: Don't always use one User-Agent, prepare a dozen mainstream browsers to randomly rotate the UA
4. Failed IPs are removed in a timely manner: Flag connection timeouts or bans immediately, don't let bad IPs drag the whole pool down!
5. Segregated use of business IPs: register with one wave of IPs, collect with another, don't let the site find out the correlation

QA time. A must-see for newbies.

Q: Do I have to use a paid proxy? Not the free ones?
A: free IP ten have nine pit, either slow as a turtle crawling, or as early as the major sites to pull black. Like ipipgo this professional service provider, IP pool hourly updates, but also with automatic forensics, save the cost of time is worth the price of admission.

Q: What should I do if I need to log in again every time I switch IPs?
A: This is a case where you have to useIP sessions with cookie retentionThe ipipgo's long-lasting IP package supports session hold function, which can be used by a single IP for 2 hours without dropping the connection.

Q: What can I do if the website uses human verification?
A: This is the time to get onHigh Stash Proxy + Browser Fingerprinting EmulationDouble protection. ipipgo's overseas residential IPs work with tools like puppeteer to effectively bypass common authentication mechanisms.

Choose the right tool for the job

In the end.Stable proxy IP services are the lifeblood of data servicesThe first is that IP purity is really high, the second is that the technical support response is fast. Used seven or eight service providers, the last lock ipipgo on three reasons: the first is the IP purity is really high, the second is the technical support to respond quickly, the third is their intelligent routing function is really cattle, can automatically match the optimal line. Recently the new pay-per-use model is also quite fragrant, small teams with no pressure.

Lastly, a note to newbies: don't wait for your account to be blocked before you remember to change your IP.Prevention is always better than cure.The following are some of the reasons for this. Putting together an auto-switching solution with a reliable IP service provider, data services can run steady and fast.
