package main

import (
"fmt"
"log"
"os/exec"
"regexp"
)

func main() {

ww, err := exec.Command("CMD", "/C", " ping 126.com").Output()
if err != nil {
log.Fatal(err.Error())
}
fmt.Println(string(ww))

ww, err = exec.Command("CMD", "/C", " ipconfig").Output()
if err != nil {
log.Fatal(err.Error())
}
// fmt.Println(string(ww))

reg := regexp.MustCompile(`\d+\.\d+\.\d+\.\d+`)
fmt.Printf("%q\n", reg.FindAllString(string(ww), -1)[0])
}
