Golang : How to convert(cast) string to IP address?

Problem :

You have IP address in string type and you want to convert(cast) the string into type IP address.

Solution :

Use the net.ParseIP() function to convert the string to type IP address (http://golang.org/pkg/net/#IP)

For example :

 package main

 import (

 func main() {

 // type string
 str := ""

 // type IP
 IPAddress := net.ParseIP(str)

 fmt.Println("4-byte representation : ", IPAddress.To4())

 // fmt.Println("16-byte representation : ", IPAddress.To16())
