Know the IP address and port number of the proxy server

Hi, dear readers! Today I would like to talk to you about IP addresses and port numbers of proxy servers. Did you know that proxy servers are like a bridge in the Internet world, connecting us to external networks. If you want to know more about proxy server and its IP address and port number, then follow me and explore!

What is a proxy server?

First, let's understand what a proxy server is. Well, a proxy server is a server that acts as a middleman, connecting and communicating on our behalf on the Internet. When we visit a website by typing a URL in our browser, our request is first sent to a proxy server, which then forwards it to the target website for us. The advantage of this is that we can hide our real IP address to protect our privacy, and it also speeds up the loading of web pages.

IP address of the proxy server

So, what is the IP address of a proxy server? Actually, proxy servers have their own IP address, which is like a virtual door number. When we connect to a proxy server, our IP address becomes the IP address of the proxy server, which hides our real identity and location.

Let's take a look at a code example to see how to get the IP address of a proxy server via Python:

import requests

def get_proxy_ip(): url = '[ ]=http'
url = 'https://api.getproxylist.com/proxy?protocol[]=http'
response = requests.get(url)
proxy_info = response.json()
proxy_ip = proxy_info['ip']
proxy_port = proxy_info['port']
print('The IP address of the proxy server is: {}'.format(proxy_ip))
print('The port number of the proxy server is: {}'.format(proxy_port))

get_proxy_ip()

With the above code, we can get the IP address and port number of a proxy server for the HTTP protocol. Of course, this is only one of the ways, in fact, there are many other ways to get the IP address and port number of the proxy server.

Port number of the proxy server

Let's talk more about the port number of the proxy server. The port number is like the gateway to the proxy server, it determines the communication channel between us and the proxy server. Each proxy server has a listening port and we need to connect to the proxy server by specifying its port number.

Typically, common proxy server port numbers are port 80 for HTTP, port 443 for HTTPS, and so on. Of course, the specific port number also depends on the type and configuration of the proxy server you are using.

How to set the IP address and port number of a proxy server

Well, now that we have learned the IP address and port number of the proxy server, how should we set them up? Actually, setting the IP address and port number of the proxy server is not difficult, we just need to configure them accordingly in our application.

Here is an example showing how to set the IP address and port number of a proxy server in Python's request library:

import requests

def get_html(): url = ''
url = 'https://www.example.com'
proxy = {'http': 'http://代理服务器IP地址:端口号', 'https': 'http://代理服务器IP地址:端口号'}
response = requests.get(url, proxies=proxy)
print(response.text)

get_html()

In the code above, we specify the IP address and port number of the proxy server by setting up a dictionary. Then, when sending a request, we can parameterize the requests library to use the proxy server we specified.

summarize

Through the introduction of this article, we have a better understanding of proxy server IP address and port number. Proxy server, as an important network tool, can help us hide our real IP address, protect privacy, speed up web page loading and so on. At the same time, we also learn how to get the IP address and port number of a proxy server and learn how to set them up.
