public

Documentation

Overview

Package public provides functions to determine your systems internet connectivity (IPv4/IPv6) and retrieve the respectively used public IP.

It uses a public service to work independently from your infrastructure. Beware! Online service: https://ip.me

You can easily replace this by changing the global variable DefaultTarget.

Functions

func IPv4

func IPv4() (net.IP, error)

IPv4 returns your IPv4 address.

Example

package main

import (
	"fmt"
	"log"

	"catinello.eu/public"
)

func main() {
	ip, err := public.IPv4()
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(ip.IsGlobalUnicast())
}

Output:

true

func IPv6

func IPv6() (net.IP, error)

IPv6 returns your IPv6 address.

Example

package main

import (
	"fmt"
	"log"

	"catinello.eu/public"
)

func main() {
	ip, err := public.IPv6()
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(ip.IsGlobalUnicast())
}

Output:

true
