Rotation of residential proxies: automatic switching of anti-blocking IPs

A rotating agent is a "cloak of invisibility" for the program.

Engaged in data collection friends understand that the target site is like a security chief, staring at each visitor's ID card (IP address). If you find the same ID frequently in and out, immediately pull the black no deal. At this timeRotation of residential agentsIt's the equivalent of preparing real IDs in bulk for a program and automatically getting a new one every few visits.

Take ipipgo's dynamic residential IP pool, their machines will randomly grab available IPs from real home broadband. for example, if you set the IP to change every 5 minutes, the program will automatically switch like a Sichuan opera face changing, and collect 100 visits in the website seems to be the operation of 100 different home users.

import requests
from ipipgo import RotatingProxy

proxy = RotatingProxy(api_key="your_ipipgo_key")
for page in range(1,101): current_ip = proxy.get_ip()
    current_ip = proxy.get_ip()
    res = requests.get(url, proxies={"http": current_ip})
    print(f "Page {page} capture complete, current IP:{current_ip}")

These are the types of situations where a rotational agent must be used

Here's a solid comparison table, so you're on the right track:

Three anti-blocking tips to remember

Tip #1: Fingerprints should match
Don't think that everything will be fine if you change your IP address. Browser fingerprints, time zone settings, and other details should match your IP address. For example, if you use an American IP and the browser language is Chinese, it's not going to be a problem.

Tip #2: Don't switch too hard
Although ipipgo's IP pool is large enough, it is recommended to adjust the switching frequency according to the business. Ordinary collection 2-5 minutes to change once, the important account operation is best to fix the same region IP with a full 24 hours.

Tip #3: Keep your network pure
Never use public proxies, those IPs have long been memorized by major websites in their little books. Residential proxy IPs are fresh home networks, like a new cell phone that just left the factory and hasn't been tagged yet.

Q&A on common pitfalls in practice

Q: The program is stuck and not moving after IP switching?
A: Check the proxy verification mechanism, it is recommended to use the connectivity detection interface provided by ipipgo and ping the target website after each switch.

Q: What if I need to open more than one IP at the same time?
A: Create multiple sub-accounts in the ipipgo background, each account is assigned an independent IP channel, so that multiple lines can be realized in parallel

Q: What should I do if I encounter a particularly difficult website?
A: Turn on ipipgo's deep camouflage mode, which will automatically match the local carrier DNS, and even the TCP fingerprints will simulate the home broadband feature

Don't get caught up in the basics.

Having seen too many people misconfigure their proxy parameters, here are a few easy points to roll over:

1. Do not write the wrong protocol header, http and https should be configured separately
2. Authentication information is recommended to be transmitted in encrypted form, not plainly written in the code
3. Set a reasonable timeout period, between 10-30 seconds is recommended

As a final note, choosing a proxy service is like looking for a date, don't just look at the price. ipipgo has a very real feature--theIP Quality RetrospectiveThe system can check the history of each IP. If an IP has been used to crawl violently before, the system will automatically block, this kind of details to see the real work.
