What does a Brazilian proxy IP really do?
Recently, a lot of cross-border e-commerce old iron asked me, why do you have to engage in the Brazilian proxy IP? For example, if you want to engage in the Brazilian local platform to monitor the price of goods, using their own network to check the data, it will be blocked by the website in a minute. At this time to get a local IP disguised as a local user, the success rate of data capture directly doubled.
There are also some brothers who work as game trainers, registering accounts for popular South American games like Free Fire with Brazilian IPs, and being able to glean exclusive campaign benefits. But here's a reminder.Don't ever do anything illegal with an agent.For example, it's no fun to get caught for malicious swiping or engaging in cyber-attacks.
Free agents have more potholes than roadkill.
Those free proxies on the Internet look pretty, but they're a real pain in the ass to use. Last week I tested 15 free services labeled "Brazilian High Speed Proxy":
| Test metrics | in the end |
|---|---|
| Average connection speed | Over 8 seconds. |
| IP Survival Time | Minimum 3 minutes |
| Request failure rate | 62% |
The darndest thing was having a proxy that popped up the login screen for a phishing site just after connecting. So yeah.Free agents are like roadside kebabs., smells good but can be bad for your stomach, especially if you need to handle sensitive data.
Teach you how to pick a reliable agent
Here's a few top tips to teach you:
1. Usecurl -x http://代理IP:端口 ifconfig.meCheck the real geographic location, many free agents flying the Brazilian flag are actually in Southeast Asia!
2. 凌晨3点测,这个时段最能看出代理的稳定性
3. Observe the frequency of IP replacement, and directly pass if the line is frequently dropped.
If it's too much trouble, just go ahead.Brazilian Exclusive IP for ipipgo,他们家在圣保罗自建机房,能控制在200ms以内。上次帮朋友调跨境电商爬虫,用他家IP连续跑了72小时没掉线。
Practical operation guide
As an example, the Python crawler is configured like this with ipipgo's proxy:
import requests
proxies = {
'http': 'http://用户名:密码@br.ipipgo.net:31028',
'https': 'http://用户名:密码@br.ipipgo.net:31028'
}
response = requests.get('http://巴西目标网站.com', proxies=proxies, timeout=10)
Remember to set the timeout parameter and switch IP immediately when you encounter lagging. ipipgo background can set the threshold for automatic IP replacement, which is especially useful for data collection.
Frequently Asked Questions QA
Q: Is it true that free proxies don't work at all?
A: temporary test can make do, long-term use is recommended to buy professional services. Just like renting a room and living in a fast hotel is okay, but you still have to live in your own house!
Q: Will ipipgo's IP be blocked by the website?
A: Their home has residential / engine room dual line, but also with automatic rotation. The blocking rate in the last three months is less than 2%, which is a big lower than the peers
Q: Why does my proxy speed fluctuate?
A: 80% is the problem of shared IP pool, change the exclusive IP immediately stable as a dog. ipipgo's exclusive line with QoS protection, speed fluctuations not more than 10%
One last word of caution.Don't save that agency money.The first thing you need to do is to get a free agent to do the job. I've seen too many people lose data by using free proxies and end up losing several times more than the proxy fee. Professional things to professional tools, efficiency is not a half a star.
