python-requests - 为什么python请求模块给出动态ip？

Question

import requests
from bs4 import BeautifulSoup

url = "http://www.whatsmyip.org"

for x in range(0,5):
    response = requests.get(url).content

    soup = BeautifulSoup(response,'lxml')
    result = soup.findAll('h1')

    for each in result:
        print each.text
        break

Output:
Your IP Address is 19.12.86.57
Your IP Address is 151.138.87.69
Your IP Address is 108.206.165.11
Your IP Address is 148.84.71.226
Your IP Address is 50.201.205.131

当我运行这段代码时，我每次都会得到一个动态 IP，而不是我的公共 IP。谁能解释一下？

我认为这不是关于 python，而是关于 whatsmyip.org ;) 他们可能检测并试图阻止脚本的某种方法。

尝试了其他一些网站，总是得到我的公共 IP。例子：

url = "https://www.iplocation.net"

for x in range(0,5):
   response = requests.get(url).content
   soup = BeautifulSoup(response, 'html.parser')
   result = soup.findAll('span')
   for each in result:
        try:
            if each.text[0] in '01234567890':
                print(each.text)
                break
        except:
            continue
