Proxy IP and IP address relationship: proxy IP and real IP relationship analysis

What is the relationship between proxy IP and real IP?

For example, if you order takeout and don't want to expose your house number, let the courier put the meal in the neighborhood station. The proxy IP is the address of that station, and the real IP is the specific building number of your house. When you use the proxy, the other party can only see the address of the station, do not know where you actually live.

Here's the point:Proxy IPs are not virtual addresses that are conjured out of thin air., but rather a real server address that exists. It's like a stagecoach is really a real building in a neighborhood, except that the address has nothing to do with the actual location of your house.

Why do you need a middleman to make a difference?

Nowadays, many websites will limit the number of visits from the same IP, for example:

• E-commerce platform against price comparison crawlers
• Social Networking Sites Against Bulk Registration
• Ticketing system to prevent ticket scalping

This is where a proxy IP is needed toAssessing the pressure of visits. For example, using ipipgo's Dynamic Residential Proxy, which automatically switches between home broadband IPs in different regions each time you visit, is much more stable than using your own real IP.

 Python Proxy Examples
import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

response = requests.get('https://目标网站.com', proxies=proxies)

How do you pick a proxy IP without stepping into a hole?

There are three main types of agents on the market:

Here's the kicker.Residential AgentsDifference between the former and the server room proxy: the former uses the IP segments assigned by carriers to ordinary households, while the latter is the IP of the server room of the data center. a lot of websites can now identify the IP of the server room, so you still have to use the residential proxy to do data collection.

Test experience sharing

Recently, I helped my friend to do some treasure data collection, and I found a little trick when I used ipipgo's dynamic proxy:Don't use the popular city IPs of the North and the South, picking agents in third and fourth tier cities has a higher success rate. For example, using the IP of Zhongwei in Ningxia is more stable than the IP of Shanghai by about 20%, which is probably due to the small number of users.

Also noteRequest interval settingsIf you change your proxy IP, you will still be blocked if your access frequency is too high. It is recommended to use with random delay:

import time
import random

 Randomly wait 3-8 seconds
time.sleep(random.randint(3,8))

QA Frequently Asked Questions

Q: Is it legal to use a proxy IP?
A: It's perfectly legal for serious uses, like market research, advertising monitoring, and all these business scenarios. But don't use it for anything illegal.

Q: Will the proxy IP be detected by the website?
A: Good quality proxies are hard to recognize. Like ipipgo's TK special line proxy, the head platform can not be detected, engaged in the crawler's friends should have a deep experience

Q: How long does a proxy IP last?
A: Dynamic proxies change IPs with each request, and static proxies are recommended to be changed every 12 hours. If you find an IP access failure, don't hesitate to change to a new one!

Q: Why do you recommend ipipgo?
A: His family has 200+ country resources, supports socks5 protocol, and the most crucial thing is to be able to1v1 Customized SolutionsThe last time a friend doing cross-border e-commerce needed to use four countries at the same time. Last time, a friend doing cross-border e-commerce needed to use four IPs from Europe, the United States, Japan and South Korea at the same time, and their tech guy matched them on the same day!

One last rant:Don't be a pain in the ass, try different types of proxies!It's a good idea to use dynamic proxies for some businesses. Some of the business with dynamic agents rather than static effect, depending on the use of the scene. If you are not sure, you can directly look for ipipgo customer service, they give the program than the Internet search is much more reliable.
