Extract IP address from ipconfig using Regex

原文 2013-06-25 12:45:07 8 2 regex/ string

I would like to extract the IPv4 address only from the output below, after running ipconfig, using Regex.

    Connection-specific DNS Suffix  . : domain.local
    Link-local IPv6 Address . . . . . : fe80::49b6:17f6:f059:1c3d%12
    IPv4 Address. . . . . . . . . . . : 192.168.2.180
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.2.254

Therefore I would like to extract the '192.168.2.180' address only.

^ *IPv4 Address[.\\s]*:\\s*([\\d.]+)\\s*$

它不会对IP地址进行任何完整性检查。

There are better ways to parse IP addresses, but this one is simple and grabs only what you need:
