在Python中读取IP地址

Question

我正在使用一个Python脚本（由一位同事编写），它获取输出文件并获取ping命令的IP地址和结果，以确定可达性状态。问题：脚本正在抓取子网掩码，而不是主机IP。我不明白为什么正则表达式与IP地址不匹配。下面是脚本生成的代码和输出文件的示例：

输出脚本示例：

Configured Address: 255.255.255.192
Destination Address: AAA.BBB.67.97
Test Status: SUCCESS!
Configured Address: 255.255.255.192
Destination Address: AAA.BBB.67.97
Test Status: SUCCESS!
Test Status: SUCCESS!
Destination Address: AAA.BBB.75.97
Test Status: SUCCESS!
Configured Address: 255.255.255.192
Destination Address: AAA.BBB.67.97
Test Status: SUCCESS!
Configured Address: 255.255.255.192

Answer 1

The script is scraping the subnet mask and not the host IP. I don't understand why the regex doesn't match the IP address.

正则表达式正在查找3个用点分隔的十进制数（由1到3个数字组成）。所以它找到子网掩码“255.255.255.192”，而找不到AAA.BBB公司.67.97英寸。在

顺便说一句，像绳子一样”AAA.BBB公司.67.97“不是IP地址。在
