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

Tags : golang lookupip ip-address convert cast

Problem :

You need to convert(cast) the integer values you get from function such as net.LookupIP() or type IP (http://golang.org/pkg/net/#IP) to string.

Solution :

Each IP address returned by net.LookupIP() has the .String() method. See example usage :

 package main

 import (

 func main() {
 addresses, err := net.LookupIP("www.yahoo.com")
 fmt.Println(addresses, err)

 for i := 0; i < len(addresses); i++ {

 segments := strings.SplitAfter(addresses[i].String(), " ") //<--- here!

 fmt.Printf("IP address #%d : %s \n", i, segments)
