Definition of IP Proxy Server

An IP proxy server is a web server that allows a client to send a request to a proxy server, which then sends the request to a destination server on behalf of the client. Its main function is to hide the real IP address of the client and provide anonymous access and access control.

Role of IP Proxy

IP proxies play a very important role on the Internet, and their role is mainly reflected in the following aspects:
1. Hide real IP address: By using an IP proxy server, users can hide their real IP address to protect their privacy and avoid being tracked or monitored.
"`ipipgothon
import requests

proxies = {
"http": "http://IP地址:端口号",
"https": "http://IP地址:端口号",
}

response = requests.get("Target website address", proxies=proxies)
print(response.text)
“`

2. Access control: IP proxy servers can set up access control lists to restrict access to specific IP addresses or geographic areas to improve network security.
"`ipipgothon
# Example Code
def check_ip(ip).
# Check if IP is in the whitelist
if ip in whitelist.
return True
else.
return False

if check_ip(requesting_ip).
# Access granted
pass
else.
# Access denied
deny_access()
“`

3. Speed up access: Some IP proxy servers can cache accessed content to reduce network transmission time and increase access speed.
"`ipipgothon
# Example Code
def get_cached_content(url).
if url in cache: if url in cache: if url in cache.
return cache[url]
else.
content = requests.get(url).text
cache[url] = content
return content
“`

Overall, IP proxy servers play an important role in protecting personal privacy, improving network security, accelerating access speeds, and are an integral part of the Internet.
