First of all, we can get proxy IPs through free proxy IP sites. these sites usually provide a large number of free proxy IP addresses, which we can get with a simple crawler program. Here is a sample code using Python:

"`ipipgothon
import requests
from bs4 import BeautifulSoup

url = 'http://www.shenlongip.com/'
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ 58.0.3029.110 Safari/537.3'}
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, 'lxml')
ip_list = soup.find_all('tr')

for ip in ip_list:
if len(ip) > 2:
td = ip.find_all('td')
print(td[1].text + ":" + td[2].text)
“`

In the above code, we use the requests library to send a request to the proxy IP site, and then use the BeautifulSoup library to parse the web page content and finally get the proxy IP address.

另外，我们还可以通过付费的代理IP服务商来获取稳定、高质量的代理IP。这些服务商通常会提供API接口，方便我们在程序中直接调用他们的代理IP资源。以为例，他们提供了简单易用的API接口，我们可以按照他们的文档说明来获取代理IP，我们只需要将YOUR_AUTH_TOKEN替换为我们在注册时获得的认证token，然后就可以直接通过他们的API接口获取代理IP了。

In general, there are many ways to get proxy IP, you can choose the appropriate way to get proxy IP according to your actual needs to improve the efficiency and security of data collection.
