How to scan proxy ip

Proxy IP has always been a topic of concern in the field of network security. This is because many malicious attackers use proxy IPs to hide their real network identity and carry out various network attacks. Therefore, real-time scanning and monitoring of proxy IPs is particularly important.

To scan a proxy IP, you first need to write a simple piece of code to implement the IP scanning function. Below is a Python code sample to demonstrate how to scan a proxy IP:

"`ipipgothon
import requests

def check_proxy(proxy).
proxy_dict = {
"http": proxy,
"https": proxy
}
try.
response = requests.get("http://www.example.com", proxies=proxy_dict, timeout=5)
if response.status_code == 200:: If response.status_code == 200.
print(f"{proxy} is a valid proxy IP")
except.
print(f"{proxy} is an invalid proxy IP")

if __name__ == "__main__".
proxy = "127.0.0.1:8080" # proxy IP address and port number
check_proxy(proxy)
“`

In the above code, we have defined a `check_proxy` function to check the validity of the proxy IP. Web requests with proxies can be realized by constructing the proxy IP as a dictionary and passing it into the `get` function of the `requests` module. If the request is successful, the proxy IP is valid, otherwise it is not.

In addition to scanning proxy IPs, many people may also want to know how to get proxy IPs. in fact, there are many ways to get proxy IPs, such as crawling proxy IP websites, using proxy IP pools and other methods. Here we take crawling proxy IP websites as an example to demonstrate how to get proxy IP.

"`ipipgothon
import requests
from bs4 import BeautifulSoup

def get_proxy_ip().
url = "https://www.example.com/proxy" # Proxy IP site address
response = requests.get(url)
soup = BeautifulSoup(response.text, "html.parser")
proxy_list = soup.find_all("div", class_="proxy-item") # Assuming that the proxy IP appears in the web page as the div tag's proxy- item class in the div tag
for proxy in proxy_list:
ip = proxy.find("span", class_="ip").text
port = proxy.find("span", class_="port").text
print(f "Proxy IP found: {ip}:{port}")

if __name__ == "__main__".
get_proxy_ip()
“`

In the above code, we send a web request using the `requests` library, and then parse the content of the web page using the `BeautifulSoup` library to finally get a list of proxy IPs.

To summarize, the scanning and use of proxy IP is an important topic in the field of network security. With the above code examples, we hope that readers can have a better understanding of proxy IP and strengthen their awareness of network security protection.
