package net
Golang net.IP.IsLoopback(), IsMulticast() and IsUnspecified() functions usage example
package main
import (
"fmt"
"net"
)
func main() {
ip4 := "127.0.0.1"
// convert to IP type
ipAdd4 := net.ParseIP(ip4)
fmt.Println("127.0.0.1 is a loopback address: ", ipAdd4.IsLoopback())
fmt.Println("127.0.0.1 is a multicast address : ", ipAdd4.IsMulticast())
fmt.Println("127.0.0.1 is an unspecfied address : ", ipAdd4.IsUnspecified())
}
Output :
127.0.0.1 is a loopback address: true
127.0.0.1 is a multicast address : false
127.0.0.1 is an unspecfied address : false
