cast – golang将一个字符串转换为net.IPNet类型

这是一个关于如何实际使用它的工作示例.

package main

import (
    "fmt"
    "net"
)

func main() {
    ipList := []string{"192.168.1.1/24","fd04:3e42:4a4e:3381::/64"}
    for i := 0; i < len(ipList); i += 1 {
        ip,ipnet,err := net.ParseCIDR(ipList[i])
        if err != nil {
            fmt.Println("Error",ipList[i],err)
            continue
        }
        fmt.Println(ipList[i],"-> ip:",ip," net:",ipnet)
    }
}
