golang编写通过cidr遍历ip地址

package main

import (
  "net"
    "fmt"
)

func (cidr string) ([]string, error) {
ip, ipnet, err := net.ParseCIDR(cidr)
if err != nil {
return nil, err
}

var ips []string
for ip := ip.Mask(ipnet.Mask); ipnet.Contains(ip); inc(ip) {
ips = append(ips, ip.String())
}
return ips[1 : len(ips)-1], nil
}

func inc(ip net.IP) {
   for j := len(ip) - 1; j >= 0; j-- {
        ip[j]++
      if ip[j] > 0 {
           break
       }
    }
}

func main()  {
    hosts, _ := hosts("192.168.11.9/27")
 for _, ip := range hosts {
      fmt.Println("sent: " + ip)
  }
}
