我正在使用Python脚本（由同事编写），该脚本接收输出文件并擦除ping命令的IP地址和结果以确定可达性状态。问题：脚本正在刮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。下面是代码和脚本生成的输出文件示例：
enter code here

源文件示例：
sh run | include ip address
ip address AAA.BBB.CCC.136 255.255.255.128
ping AAA.BBB.67.97
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to AAA.BBB.67.97, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 142/142/143 ms
ping AAA.BBB.75.97
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to AAA.BBB.75.97, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 134/134/135 ms
示例脚本输出：
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
Destination Address: AAA.BBB.67.97
Test Status: SUCCESS!
Test Status: SUCCESS!
Destination Address: AAA.BBB.75.97
Test Status: SUCCESS!
答案 0 :(得分：0)
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。
您的正则表达式正在查找用点分隔的3个十进制数字（由1到3位数字组成）。所以它找到子网掩码＆＃34; 255.255.255.192＆＃34;虽然它没有找到＆＃34; AAA.BBB.67.97＆＃34;。
顺便说一句，字符串如＆＃34; AAA.BBB.67.97＆＃34;是不一个IP地址。
