Acquisition Proxy IP: Data Acquisition Proxy IP Configuration Optimization Solution

Hands-on! Hands on with choosing the right proxy IP type

What's the worst thing about data collection? Just grabbing two pages.IP blockedThe wrong type of agent is like running a marathon in flip-flops! Choosing the wrong type of proxy is like running a marathon in flip-flops, the longer you run, the more your feet hurt. There are three main types of proxy IPs that we encounter on a daily basis:

Dynamic Residential IPThe most like real people surfing the Internet, each request for a new IP. suitable for scenarios that need to simulate the behavior of real users, such as grabbing limited edition sneakers. Take ipipgo's dynamic residential package, 7 dollars more than 1 G of traffic, enough for you to grab hundreds of thousands of commodity information.

Static Residential IPIdeal for businesses that need to maintain login status for a long time, let's say keeping social media accounts. Although 35 dollars an IP looks expensive, but can guarantee 7 consecutive days without dropping, much more cost-effective than being blocked.

 Python Example: Dynamic Agent Rotation
import requests
from itertools import cycle

proxy_pool = ['111.222.33.44:8000', '222.111.55.66:8000']
proxy_cycle = cycle(proxy_pool)

for page in range(1,100): proxies = {"http_pool")
    proxies = {"http": next(proxy_cycle)}
    response = requests.get('https://目标网站', proxies=proxies)

The devil's details in the configuration parameters

Ever seen someone deliver tofu in a Ferrari? A good agent has to come with good parameters. Here are a few easy potholes to step into:

1. timeout settingDon't copy the tutorial! According to the target site response speed dynamically adjusted, it is recommended to use 5 seconds to test, and gradually shorten to 2 seconds after stabilization!

2. request header fingerprintBe like a chameleon. Don't just change User-Agent, remember to randomize the cold parameters like Accept-Language and Connection as well!

3. fail and try againWith delay. Continuous retries are the same as holding up a sign that says "I'm using an agent", so it is recommended to use an exponential backoff algorithm.

Practical case: e-commerce price monitoring system

Last year to help a clothing company to do competitive monitoring, they have to grab 50,000 pieces of data every day. With ipipgo's Dynamic Residential (Enterprise Edition) package, along with the following configuration plan, it ran stably for 8 months:

Frequently Asked Questions QA

Q: What should I do if the proxy IP speed is fast or slow?
A: 80% of the protocol is not selected correctly! HTTP protocol is suitable for ordinary web pages, HTTPS go encrypted traffic, Socks5 is more friendly to video resources. ipipgo's client can automatically match the best protocol!

Q: How do I break the CAPTCHA when I encounter it?
A: Don't be rigid! Immediately switch the static residential IP, the request delay to 30 seconds or more, with real people operating track simulation. ipipgo's TK line is designed to deal with this!

Q: How do I choose a package with a limited budget?
A: first take the dynamic standard edition to test the water, 7.67 yuan / GB enough to catch 100,000 level data. After the volume up to the enterprise version, 9.47 dollars but support higher concurrency. Remember to open the traffic warning, do not exceed the speed limit!

The Ultimate Killer: IP Fingerprint Obfuscation

Last year I had a client who did airfare comparison and was always recognized by the backcrawler. Later, I used ipipgo'scross-border rail line+ These three tricks took care of that:

1. Decentralize requests to different country nodes (don't use all US IPs)
2. Random insertion of 0.5-3 seconds of mouse trajectory
3. Weekly replacement of 20% IP pool with a mix of old and new IPs

Now they are steadily catching 200,000 flight data per day, and they are still using Dynamic Residential Enterprise Edition. Remember, proxy IP is not a panacea, it has to be combined with the right tactics to maximize its power.
