Why is it always said that IP proxies are like courier staging areas?
Have you ever thought of using IP proxies when you use them, this thing is actually very similar to courier outlets? For example, if you order tea from Hangzhou in Beijing, and if the merchant uses Shanghai's transfer station to deliver the goods, the logistics information will show that the goods are sent from Shanghai, and the IP proxy is also the same reasoning - hiding the real address, and using the address of the proxy server to contact the outside world. However, there is a pit here, many free proxies are just like the paper boxes picked up on the side of the road, and may leak one day.
Who in their right mind uses a static IP?
There are two main types of agents on the market today:static IPrespond in singingdynamic IP. Static IP is like a landline phone, which does not move 24 hours a day, and is suitable for scenarios that require long-term stable connectivity, such as enterprise-level data monitoring. But there is an Achilles heel -Easily blockedIt's like having the same car parked in front of your house every day. It's like parking the same strange car in front of your house every day, sooner or later the security guards are going to check it.
Dynamic IP is the real flavor choice, especially those who do data collection should know it well. For example, with ipipgoDynamic residential agent pool, automatically switching home broadband IPs across the country with each request, realism pulls straight through. Look at this Python example to understand:
import requests
proxy = "http://user:password@gateway.ipipgo.com:9020"
url = "https://target-site.com"
response = requests.get(url, proxies={"http": proxy, "https": proxy})
print(response.text)
Three Tips for Raising a Good IP Resource Library
Maintaining a proxy IP library is like keeping fish, it has to be done right:
1. geographic rotation strategyDon't be so particular about a province that you use a Jiangsu IP today and a Fujian IP tomorrow.
2. Survival detection scripts
3. Agreement Matching Principle
I have a friend who does e-commerce price comparison and always complained about IP blocking before. Then he switched to ipipgoMixed Agent Package, using the HTTP and SOCKS5 protocols separately, with their smart routing, the survival rate shot straight up from 50% to 92%.
A must-see guide to avoiding the pitfalls for beginners
Three common mistakes newbies make:
① blind pursuit of low latency: in fact, the delay of about 200ms is the most secure, those who claim that 50ms of ultra-fast proxy, 80% of the IP room!
② ignore the response code: see the 200 status code, think success, the result is returned to the verification page
③ Single-IP high-frequency requests: even with a dynamic IP, sending 50 requests a minute is suspicious enough.
QA time
Q: Is it legal to use a proxy IP?
A: Just like a kitchen knife can cut vegetables or hurt people, the key depends on the use. To do data collection, localization testing, these serious purposes is perfectly fine, remember to choose ipipgo this kind of formal qualifications of the enterprise!
Q: What should I do if my agent is slow?
A: Check the local network first, then try switching protocol types. ipipgo'sIntelligent Routing SystemAutomatically selects the optimal route, more than three times faster than manual switching
Q: How do I test if the agent is valid?
A: It's accurate to use this earthly method:
curl --connect-timeout 5 -x http://代理IP:端口 http://httpbin.org/ip
Resource library building practice
Finally, give a practical program:
1. Register for a ipipgo developer account
2. Created on the consoleDynamic Residential Agentsconduit
3. Use their API to get a list of live IPs
4. with scrapy middleware do automatic rotation
Here's a little trick: the proxy IP by province stored in different database tables, collection according to the target site location call the corresponding IP, pro-test sealing rate can be reduced to 60%.
In the end, choosing the right service provider is half the battle. ipipgo'sCity-level positioningrespond in singingReal User Behavior SimulationTechnology, indeed, is much more reliable than those with virtual machine IP. Recently, they are engaged in activities, new users to send 10G of traffic, it is recommended to go to woolgathering first to try the water.
